[SOLVED] Pacman linux update mkinitcpio hook uses old kernel version

khouli · 2018-02-01 18:18:01

Whenever I use pacman to update the linux package, it creates an initramfs image based on the running kernel version instead of the updated kernel version. Since pacman also deletes the modules directory of the old/running kernel version, this breaks my boot.

I can fix this by running mkinitcpio and manually specifying the new kernel version with the -k flag, but it seems like the builtin pacman linux hook is supposed to be doing this.

Here's the relevant output from pacman when updating linux:

# pacman -Syu linux
[...]
==> Building image from preset: /etc/mkinitcpio.d/linux.present: 'default'
  -> Starting build: 4.14.15-1-ARCH
[running build hooks]
==> Generating module dependencies
==> Creating gzip-compressed initcpio image: /boot/initramfs-linux.img
==> Image generation successful

There are no error messages and it looks like pacman has successfully running mkinitcpio but this breaks my boot and probably isn't the intended behavior of pacman.

It seems like this is just an issue with my pacman config, but just in case here's some more info about my system. My boot partition is mounted and writable when I run the pacman update. mkinitcpio does write to /boot/initramfs-linux.img and changes the mtime and ctime. My boot partition is on a separate disk than my root partition. Here's it's fstab entry:

UUID=5ADA-42D7 /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2

Besides the UUID, those options have simply been grandfathered over in their original state (probably an old Arch install).

If I boot from a live media, chroot into my system root, and run pacman, it updates my initramfs properly.

mkinitcpio -p itself also fails but it correctly errors out and reports that it couldn't find the modules directory for the kernel it was trying to create an image for.

Thanks.

We'll need full logs.

Here's an install of linux from the system after manually fixing the initramfs:

Would anything else be helpful? I could break things again and get more logs by reinstalling the cached version of the previous linux package if that would help.

Yes please downgrade linux to the last version from the cache and post the output from that command and after that the output of

bsdcpio -it < /boot/initramfs-linux.img

Scimmia · 2018-02-01 18:44:13

That log shows it building the initramfs for the correct kernel, so no problems there.

khouli · 2018-02-01 19:13:34

I downgraded back to Linux 4.14-10-1. This actually also broke my system and I had to manually create the 4.14-10-1 initramfs. After getting back to a bootable 4.14-10-1 system, there's a log of using pacman to upgrade linux that broke my boot:

Boot breaks because the system can't mount /boot because it couldn't load the vfat kernel module. Some commands from emergency mode (transcribed by hand so small chance of typos):

# uname -r
4.14.10-1-ARCH
# ls /lib/modules
4.14.15-1-ARCH extramodules-4.14-ARCH

pacman reports the installed linux package is 4.14.15-1.

I saved the output of bsdcpio -it < /boot/initramfs-linux.img from emergency mode, but somehow while going back and forth I've borked my system fairly heavily so I can't post that just yet.

This *should* be categorically impossible, as that is precisely what pacman itself does.

$ cat /usr/share/libalpm/hooks/90-linux.hook 
[Trigger]
Type = File
Operation = Install
Operation = Upgrade
Target = boot/vmlinuz-linux
Target = usr/lib/initcpio/*

[Action]
Description = Updating linux initcpios...
When = PostTransaction
Exec = /usr/bin/mkinitcpio -p linux

So I don't understand how the same mkinitcpio command when run as a PostTransaction hook in pacman, can successfully complete, report that it is building against the correct kernel in the process, and end up with the wrong kernel inside the cpio image, while immediately running the same command after pacman, cannot detect the modules directory. This is rather odd!

What is the exact mkinitcpio error? Also loqs' suggestion would help.

EDIT: Okay, thanks. So somehow, mkinitcpio is proceeding as expected, writing a new initcpio to /boot, which you then boot from, but somehow /boot also still has the vmlinuz from linux 4.14.10-1???

It sounds almost like something is *copying the old vmlinuz back* after the pacman hook runs, but before you try running mkinitcpio by hand or rebooting.

Since it's actually booting the old kernel, that tells me your bootloader configuration is messed up. It's somehow still finding the old kernel even after it's been updated.

I've unborked things. First, here's that log of bsdcpio -it < /boot/initramfs-linux.img from emergency mode after upgrading to linux-4.14.15-1 from a system running Linux 4.14.10-1 and rebooting:

Right now I'm at a working 4.14.15-1.

It sounds like a log of mkinitcpio -p linux from 4.14.10-1 after a pacman -Su linux would be useful. Anything else?

Installing the cached linux 4.14.10-1 from a running 4.14.15-1 does also break my initramfs btw.

Scimmia · 2018-02-01 20:56:02

Your initramfs is fine. Your bootloader and/or partition mounting is the problem. Look there.

loqs · 2018-02-01 20:56:40

The config for the bootloader the system uses and the output of `cat /proc/cmdline` If you unmount /boot is there a kernel in the /boot directory or the root filesystem?

khouli · 2018-02-01 21:15:54

Using bsdcpio some more, I've found that /boot/initramfs-linux.img is being changed between pacman finishing and reboot failing.

What I said earlier about mkinitcpio -p linux failing was misleading by the way. It only fails after I'm in emergency mode and already have a mismatching kernel and modules directory.

EDIT: Nevermind, I think that's wrong. I was comparing the output of bsdcpio from a working system and a system that failed to mount /boot.

Are you going to start responding to posts or are we just done here?

khouli · 2018-02-01 21:41:01

It looks like I've been writing to /boot when /dev/sda2 is mounted there (intentional) and also when nothing is mounted there and it's just a directory under / (not intentional) and that's a big part of my confusion.

Sorry Scimmia, I'm not trying to ignore anyone. I'm trying to get back to a bootable system so I can get the info about my boot config. I was just trying to post what might be a useful observation in the meantime.

There are indeed separate kernels in the properly mounted /boot and the unmounted /boot and they've both been written to today. Hmmm... It looks like loqs nailed it. I've been writing into more than one /boot and I just need to figure out how to aim grub at the initramfs-linux.img in intended location which is /dev/sda2.

Anything else I forgot to respond with? Thanks again.

EDIT: Here's my fstab to help make sense of the UUIDs

# Static information about the filesystems.
# See fstab(5) for details.

# <file system> <dir> <type> <options> <dump> <pass>

I haven't quite figured out how to tell grub to do the right thing, but I understand the problem now and I should be able to take it from here. Thanks.
