MX Linux Forum

Posted: **Tue Dec 03, 2024 12:50 am**

(I don't want to go back to Grub Customizer)

I have the menu set up in flat mode currently and (through this forum) found how to edit the names of the entries to make it easier to find them.

grub.jpg

What I would like to do is have just three entries showing in this order.

Fluxbox-6.6
(this menuentry 'fluxbox, with Linux 6.6.63-x64v3-xanmod1 (systemd))

XFCE-6.1
(this menuentry 'XFCE, with Linux 6.1.0-28-amd64 (systemd))

Fluxbox-6.1
(this fluxbox, with Linux 6.1.0-28-amd64 (systemd))

I have searched through the forum which is how I found out how to edit the names but not anything regarding grub itself.
If I missed a thread, please point me in that direction.

This is my grub.cfg file.

1) /boot/ (kernels and initrd are stored here - feel free to have a look. It might surprise you what old kernels you still have lying around)
2) /etc/grub.d/ (snippets/small files)

this is where the config file is getting stuff like this from:

### BEGIN /etc/grub.d/05_debian_theme ### <-------------------- actually a file
set menu_color_normal=cyan/blue
set menu_color_highlight=white/blue
### END /etc/grub.d/05_debian_theme ###

3) /etc/default/grub (standard grub file that you are supposed to do minor edits - MUST BE FOLLOWED by the 'sudo update-grub' command for the changes to take effect)

It is generally not recommended to edit the grub.cfg file because it is auto-generated after a kernel update or if you do update-grub. Either of those events will undo any changes.

As things stand you have 3 choices:

1) TEMPORARY - edit the grub.cfg (safer in my opinion)
2) ADVANCED PERMANENT - check what kernels you have installed, remove any that you don't need, then edit the 2 snippet files (SEE BELOW) followed by sudo update-grub. IF YOU EDIT THE GRUB.CFG ONLY, DO NOT DO UPDATE-GRUB.
3) use a graphical tool - I used to use grub-customizer but I am not sure if it is in the newer repos. Even back then, it was no longer maintained or had issues.

* MX Boot Options doesn't seem to have options to delete/rename/move entries around

Look through each of the entries and cut and paste, move them around as you wish. Just be careful that you copy full sections.

If you want, you can have the grub.cfg file open and an empty file and just paste the sections that you want into it. Once you are happy with it, post it here and one of the devs can check it for you. Alternatively, somebody might suggest a GUI tool for you.

I believe the key script in /etc/grub.d/ directory is the file named 10_linux

If you don't mind the whole normal grub menu appearing below, I can suggest a way to place your 3 favourite grub menu entries at the top, by creating a /boot/grub/custom.cfg file, and then renaming /etc/grub.d/41_custom as /etc/grub.d/09_custom.

The 41_custom script is the one that reads what's in custom.cfg and lists them on the grub menu page. By numbering it 09, ie, earlier than the 10_linux script that creates the menu entries in grub.cfg, your custom entries will be displayed first.

I have been using this for a long time on my multiboot machine. Nice and permanent, yet easy to edit anytime you want to change what's in custom.cfg.

No update-grub needed!

Posted: **Tue Dec 03, 2024 7:33 am**

I can confirm that grub-customizer is in Debian 12 repos.

I know you said you don't want to go back to grub-customizer but what you could also do is:

1) install grub-customizer,
2) make the changes you want
3) have a look at the new grub.cfg that grub-customizer has generated (copy or save it)
4) uninstall grub-customizer
5) Have a look at the grub.cfg again. If it is back to the original, rename it AND replace it with the grub-customizer copy.

Posted: **Tue Dec 03, 2024 8:46 am**

I believe grub-customiser creates their own version of the boot menu elsewhere, they don't ever write over the original grub.cfg.

The problem with GC is that sometimes it creates double and triple copies of their boot menu, especially when somehow you see more than one copy of os_prober get copied into their boot menu. The copies may multiply over time.

That was my experience using it but that was more than 10 years ago, though I don't think it's been updated much.

Good. Grub Customizer has shown to create issues, at least in MX Linux. So my personal recommendation don't use.

siamhie wrote: ↑Tue Dec 03, 2024 12:50 am I have the menu set up in flat mode currently and (through this forum) found how to edit the names of the entries to make it easier to find them.

Do not edit /boot/grub/grub.cfg, b/c it get's overwritten next update-grub run:

Code: Select all

# DO NOT EDIT THIS FILE
#
# It is automatically generated by grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
#

To adjust resp menu title entries, you may adjust two lines, the first and the last within /etc/lsb-release:

Code: Select all

PRETTY_NAME="MX 23.4 Libretto"
DISTRIB_DESCRIPTION="MX 23.4 Libretto"

E.g. on Fluxbox install change to

Code: Select all

PRETTY_NAME="MX Fluxbox"
DISTRIB_DESCRIPTION="MX Fluxbox"

update-grub will scan for all installed kernels, so you can only reduce the number of kernels by removing old kernels.
And by default will also scan for both sysvinit an systemd entries.
But this can be tweaked easily to only show systemd entries. Later more if you are interested.

I thought it would be easier to respond to all three of you at once currently.

Since it says this at the top of the grub.cfg file "# DO NOT EDIT THIS FILE", I will not be editing this file.
I tried grub-customizer during my MX-21 days and think I had issues which is why I don't want to revisit that program.

I would like to have just three entries on my grub screen all booting systemd.

I would like to know more on this custom.cfg file you mention. Would I edit my grub.cfg file to my liking and save it as custom.cfg in the boot directory?
Then save the 41_custom file as 09_custom in the /etc/grub.d/ directory?

@siamhie you said:

Then save the 41_custom file as 09_custom in the /etc/grub.d/ directory?

My suggested way will NOT give you ONLY 3 entries on the on-screen boot menu, since the grub.cfg entries will come after whatever is in custom.cfg. However, you will have your favourite custom entries right at the top.

Plus:
1] it's safe and quick to do and subsequently edit. No messing with or editing the actual scripts in /etc/grub.d/ beyond renumbering 41_custom.
2] no need to touch or edit grub.cfg at all
3] No need to update-grub whenever you edit the custom.cfg file.

All you have to do is to create a file called /boot/grub/custom.cfg, and copy and paste whatever grub entries you choose from the grub.cfg file into custom.cfg.
The reason for renumbering 41_custom to 09_custom, is so that your system reads 09_custom before 10_linux, and places your custom entries before the boot entries in grub.cfg. Otherwise your custom entries will be placed after your grub entries.

Below, I set out the custom.cfg file with the 3 entries you want. However note that the first 5 lines may not actually be necessary. When I first started, I wasn't sure, so I simply copied these starting lines from the beginning of the /etc/grub.d/40_custom script, which is a totally different method of adding custom entries which does require updating grub every time. This is not necessary for custom.cfg, which will be read by the 41_custom script.

You may wish to open 41_custom script to see what it does.

Also, when you install new kernels, you will need to read the newly generated grub.cfg and copy and paste the correct entries into custom.cfg.

Code: Select all

For me, as I have about 13 or 14 different Linux distros installed on my PC, I can't be booting into my main distro to update grub whenever there is a kernel upgrade in a distro, so I label all my distro partitions, and made custom entries to read the custom.cfg grub.cfg file of whichever distro I chose. What this does is when I select a custom entry, it calls up a second menu, namely the grub.cfg of the selected distro, and I then boot into the necessary boot entry in the distro I selected.

Below, I set out the first 2 entries in my custom.cfg. I just threw in a whole lot of insmod lines for each of my menu entries, some will be more applicable than others for each distro.

For instance, /dev/sda has legacy msdos partition table, while /dev/sdb is gpt partition table:

*Btw, I do have a current snapshot in case anything goes wrong during this learning experience.

I just posted the custom.cfg contents just above your post. You don't need all the bits you included.

I would like to know more on this custom.cfg file you mention. Would I edit my grub.cfg file to my liking and save it as custom.cfg in the boot directory?
Then save the 41_custom file as 09_custom in the /etc/grub.d/ directory?
My suggested way will NOT give you ONLY 3 entries on the on-screen boot menu, since the grub.cfg entries will come after whatever is in custom.cfg. However, you will have your favourite custom entries right at the top.

Seems you responded just as I was typing a new comment. I did look at the contents of 41_custom and had a question.

Code: Select all

#!/bin/sh
cat <<EOF
if [ -f  \${config_directory}/custom.cfg ]; then
  source \${config_directory}/custom.cfg
elif [ -z "\${config_directory}" -a -f  \$prefix/custom.cfg ]; then
  source \$prefix/custom.cfg;
fi
EOF

Does this also get added to my custom.cfg file at the end?

No. The custom.cfg is a pretty clean file with just the boot entries you want. Don't change 41_custom and just let it do its thing.

Ok, so just run my usual sudo update-grub from terminal then? (I will monitor the output of what displays on the screen)

No update grub needed. Just edit the custom.cfg and reboot. That's it.

Perhaps post the custom.cfg you have created under /boot/grub/custom.cfg as text code-block.
This is to avoid any potential typos within that file, may stop to show the added entries,
and you might wonder what's going on.
E.g this way:
Open terminal as normal user and run:

Code: Select all

xclip -selection clipboard -i /boot/grub/custom.cfg

This would send the content of custom.cfg into the "clipboard".
Now within the editor of a reply post, click on [</>] code-block icon,
to get the code-block tags inserted - thos guys: [code][/code]
The cursor is now located between the code block tags.
Press Ctrl+v to paste the custom.cfg from the clipboard.

Just saw this post. I had updated grub and I'm close but no quite there.
Seems my custom.cfg entries were added to the end of my grub menu.

Ah OK. That's how my custom.cfg started when I wrote it and I added the other sections from the grub.cfg file thinking I needed them.
Grub still confuses me compared to the LILO days.

I'll edit the custom.cfg file back to what I originally had it. Do I still run update-grub afterwards?

Posted: **Tue Dec 03, 2024 11:17 pm**

No. No update grub needed. EVER. The custom.cfg file is just a list of grub entries. No scripting bits.

I mean, I gave you the whole contents of the custom.cfg for you to copy and paste quite a few posts ago.

Posted: **Tue Dec 03, 2024 11:24 pm**

If your custom.cfg entries are at the end of normal grub entries, did you remember to renumber 41_custom?

I had gotten that but cleaned up the menuentries.

@asqwerth I had actually created a /boot/grub/custom.cfg file with those three entries and let 41_custom do it's thing.

Code: Select all

#!/bin/sh
cat <<EOF
if [ -f  \${config_directory}/custom.cfg ]; then
  source \${config_directory}/custom.cfg
elif [ -z "\${config_directory}" -a -f  \$prefix/custom.cfg ]; then
  source \$prefix/custom.cfg;
fi
EOF

I still end up with the new entries at the bottom of the grub screen.

I have now copied the contents of /boot/grub/custom.cfg to /etc/grub.d/40_custom and deleted the /boot/grub/custom.cfg file.

One thing I did notice is that MX Boot Options never picked up on the /boot/grub/custom.cfg file but since I transferred those entries to 40_custom, MXBO picks them up.

mxbo.jpg

I will now try your earlier suggestion to rename 40_custom to 09_custom and it should put my entries at the beginning.

Posted: **Wed Dec 04, 2024 9:54 am**

If you copy the menu items to 40_custom, then you NEED to update-grub every time you change the contents of 40_custom. It just doesn't work the same way as 41_custom + the custom.cfg file.

Script numbers 40 and 41 do things differently.

Things in custom.cfg won't be picked up by grub or MX boot options because it's not part of grub.cfg. It's just a separate list of custom entries from grub.cfg, that 41_custom script can detect and tag on to the grub menu. If you renumber 41 to 09, then the script adds it before the grub.cfg entries, otherwise the custom.cfg entries are tagged on after the grub.cfg entries.

40_custom is different. For this script, you are SUPPOSED to add the custom entries to ths 40_custom file itself, and then update-grub. That way, it is seen together with grub.cfg. I guess you can try renumbering it as 09 and see what happens.

I don't use 40_custom on my system because I don't want to update-grub all the time

I only update grub when Xanmod releases a new 6.6 LTS kernel they have grabbed from the archives.
Debian's 6.1 LTS kernel doesn't get updated often which is my backup kernel for fluxbox and main kernel for XFCE.

So the only entry I would have to edit the most is this one.

Code: Select all

menuentry 'Fluxbox-6.6' --class fluxbox --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-6.6.63-x64v3-xanmod1-init-systemd-20cfcd8f-3e81-49d4-a5f4-35784be52c3f' {

I suppose this will be as close to a custom grub menu with only three entries showing as I will get.
At least they are at the top now.

To be honest, not only did the title of the topic lead to confusing
assumptions right from the start, but now the adjustments you have made
are causing even more confusion (at least for me).

May I suggest the following: Just rephrase what you are trying to
accomplish, and post all the relevant changes you have made so far, I
mean the files you have customized. Otherwise, I don't think I can give
any more tips without fear of adding to the confusion.

I apologize for the confusion the thread has turned into. The title of the thread was editing grub by hand and this is what I started my post with.

I have the menu set up in flat mode currently and (through this forum) found how to edit the names of the entries to make it easier to find them.

What I would like to do is have just three entries showing in this order.

Fluxbox-6.6
(this menuentry 'fluxbox, with Linux 6.6.63-x64v3-xanmod1 (systemd))

XFCE-6.1
(this menuentry 'XFCE, with Linux 6.1.0-28-amd64 (systemd))

Fluxbox-6.1
(this fluxbox, with Linux 6.1.0-28-amd64 (systemd))

So to sum up what I have done is this.

1. copied the contents of /boot/grub/custom.cfg to /etc/grub.d/40_custom and saved the 40_custom file as 09_custom

Code: Select all

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

	echo	'Loading initial ramdisk ...'

}

	insmod gzio
	if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
	insmod part_gpt
	insmod ext2
	search --no-floppy --fs-uuid --set=root 20cfcd8f-3e81-49d4-a5f4-35784be52c3f
	echo	'Loading Linux 6.1.0-28-amd64 ...'
	linux	/boot/vmlinuz-6.1.0-28-amd64 root=UUID=20cfcd8f-3e81-49d4-a5f4-35784be52c3f ro  quiet init=/lib/systemd/systemd
	echo	'Loading initial ramdisk ...'
	initrd	/boot/initrd.img-6.1.0-28-amd64
}

2. deleted /boot/grub/custom.cfg
3. updated grub and my three custom entries were now at the top of every thing else

The next steps I did might not be right or correct but it worked (for my scenario)

4. removed the executable permissions from 10_linux, 20_linux_xen, 20_memtest86+,
30_os-prober, 30_uefi-firmware, 40_custom and 41_custom
5. updated grub

Now I have just the three entries I wanted showing and I can choose which one to be default in MX Boot Options.

OK, thanks.
The picture got now a bit clearer.
So what you want, is disable generation of grub menu entries, and have your own. OK fine.
And you would need manually adjust the grub menu after every kernel upgrade, or removal
Probably one way to go, but that not what I would recommend in general to do.
Anyway, good luck.

	initrd	/boot/initrd.img-6.1.0-28-amd64
}

To avoid a potential issue, with booting into latest installed kernel,
e.g. just after kernel upgrade, and you missed manually adjusting the grub menu:
You may try this menuentry, potentially to be put on top,
e.g. as an example for fluxbox:

Code: Select all

menuentry 'Fluxbox latest kernel installed' --class fluxbox --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-latest-installed-init-systemd-20cfcd8f-3e81-49d4-a5f4-35784be52c3f' {
	load_video
	insmod gzio
	if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
	insmod part_gpt
	insmod ext2
	search --no-floppy --fs-uuid --set=root 20cfcd8f-3e81-49d4-a5f4-35784be52c3f
	echo	'Loading Linux latest installed ...'
	linux	/vmlinuz root=UUID=20cfcd8f-3e81-49d4-a5f4-35784be52c3f ro  quiet init=/lib/systemd/systemd
	echo	'Loading initial ramdisk ...'
	initrd	/initrd.img
}

The difference is , latest kernel installation creates alway two symlinks /vmlinuz and /initrd.img:
E.g in the example above as:

Code: Select all

/vmlinux  -> boot/vmlinuz-6.6.63-x64v3-xanmod1
/initrd.img -> boot/initrd.img-6.6.63-x64v3-xanmod1

As those symlinks are relative symlinks, you can use it as booting into latest installed.
Similar would be, /vmlinuz.old and /initrd.img.old pointing to the one which was previous the latest.

The picture got now a bit clearer.
So what you want, is disable generation of grub menu entries, and have your own. OK fine.
And you would need manually adjust the grub menu after every kernel upgrade, or removal
Probably one way to go, but that not what I would recommend in general to do.
Anyway, good luck.

My days of chasing/experimenting with the latest kernels are done. I'm sticking with the LTS kernels (Xanmod-6.6 and Debian-6.1).
If either of those kernels have an update, I can always re-enable the executable flag for 10_linux and 30_os-prober and copy the
entry found in the grub.cfg file and apply it to the 09_custom file.

I'll go ahead and mark what I did in post #28 as solved.

Seems you have responded before I could publish post #31.

So at least you now have a fallback in case you missed to adjust the grub menu manually.

Yes. Always have a backup and then have a backup for that backup.

@fehlix Wanted to give you an update on adding kernels with my setup. What a breeze.

I re-enabled the executable flag for the /etc/grub.d/10_linux file.
Installed the Liquorix kernel from the repos. Let the installation update grub.
Copy the (systemd) Liquorix entry from grub.cfg to my /etc/grub.d/09_custom file.
Disable the executable flag for the /etc/grub.d/10_linux file.
Ran sudo update-grub.

Thanks @asqwerth

Between you and @fehlix bouncing ideas around, I think I have a handle now on customizing grub.

I still miss the simple days of LILO.
