[SOLVED] mkinitcpio add_udev_rule: command not found

Greetings everyone!

Since my last full upgrade I'm being dropped to an emergency console when booting and I'm told my root device with UUID=... was not found. I narrowed it down to the lvm2 module not being present in the initramfs image.
I chrooted into the filesystem and ran $(mkinitcpio -p linux) which yielded:

  -> -k /boot/vmlinuz-linux -c /etc/mkinitcpio.conf -g /boot/initramfs-linux.img

I also found https://bugs.archlinux.org/task/72598 where it is suggested to upgrade systemd to 249.5-3 when using lvm2 2.03.14-1.

This however did not work since I'm running the latest versions:

Package (3)      Old Version  New Version  Net Change  Download Size

core/lvm2           2.03.14-1   2.03.14-1    0.00 MiB      1.51 MiB
core/mkinitcpio   30-2          30-2           0.00 MiB       0.04 MiB
core/systemd     249.5-3      249.5-3      0.00 MiB       6.45 MiB

Re: [SOLVED] mkinitcpio add_udev_rule: command not found

I solved the issue by changing the position of the lvm2 hook in /etc/mkinitcpio.conf from

HOOKS=(lvm2  base udev ... block filesystems)

to

HOOKS=(base udev ... block lvm2  filesystems)

I don't know why the first order worked until now and why it does not anymore. Anyway, it works again using the new order of hooks!
