Bug 408195 – sys-boot/grub-2.00_beta2: grub2-mkconfig, kernels not sorted by version

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Daniel Schömer 2012-03-14 18:49:07 UTC]

grub2-mkconfig does not sort the available kernels in /boot/ by their versions.

Reproducible: Always

Steps to Reproduce:
1. Copy different kernels to /boot/ (I used genkernel), lets say kernel-genkernel-x86_64-3.2.6-gentoo, kernel-genkernel-x86_64-3.2.9-gentoo and kernel-genkernel-x86_64-3.2.11-gentoo
2. Run "sudo grub2-mkconfig -o /boot/grub2/grub.cfg"
Actual Results:  
$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub.cfg ...
Found linux image: /boot/kernel-genkernel-x86_64-3.2.9-gentoo
Found initrd image: /boot/initramfs-genkernel-x86_64-3.2.9-gentoo
Found linux image: /boot/kernel-genkernel-x86_64-3.2.6-gentoo
Found initrd image: /boot/initramfs-genkernel-x86_64-3.2.6-gentoo
Found linux image: /boot/kernel-genkernel-x86_64-3.2.11-gentoo
Found initrd image: /boot/initramfs-genkernel-x86_64-3.2.11-gentoo
Found memtest86+ image: /boot/memtest86plus/memtest
done

# The kernel order is 3.2.9, 3.2.6, 3.2.11

Expected Results:  
Generating grub.cfg ...
Found linux image: /boot/kernel-genkernel-x86_64-3.2.11-gentoo
Found initrd image: /boot/initramfs-genkernel-x86_64-3.2.11-gentoo
Found linux image: /boot/kernel-genkernel-x86_64-3.2.9-gentoo

done

# The kernel order is 3.2.11, 3.2.9, 3.2.6

The error is in /usr/share/grub/grub-mkconfig_lib, line 196, bash function version_sort().

To sort the kernel versions, sort (/usr/bin/sort) is used with option -V (version sort), if available. The test if sort accepts option -V (uppercase), actually tests if -v (lowercase) is accepted.

After changing the test to really test if -V is accepted, the kernels are listed in the correct (descending) version sort order.

Patch /usr/share/grub/grub-mkconfig_lib to test for "sort -V"

Yeah, I reported that upstream on Monday. See URL.

[Comment 4 Geoff Madden 2012-03-19 06:27:51 UTC]

I ran into a curious problem ,due to the non sorting I deleted all but the 3.2.11 branch and when rerunning grub-mkconfig it did not pick up the existing kernel in boot,this happened on both x86 /x86_64 both AMD machines.
Any ideas ????????

It sounds like you deleted all your kernels, not just the old ones.

Please ask for support in an official support channel (not bugzilla). Personally, I hang out in #gentoo quite often, so feel free to ping me there.

This has been fixed upstream. I'll keep this open until beta3 is in the tree.

I've searched upstream bugtracker and reported
https://savannah.gnu.org/bugs/index.php?35888
on Sunday.

Can you please add an revbump -r1 with this patch included?
I ran into this isse several times esp. with kernels 3.2.9 and 3.2.11.

Thanks
