Starting from commit https://github.com/dracutdevs/dracut/commit/3d8e1ad2ae1e34244ddf700beea6358c1452e05c, dracut stopped chrooting into initramfs on shutdown:

ERROR: src/skipcpio/skipcpio.c:91:main(): Cannot open file '/efi/6699e6fad149423fa9fe8ac1c19e1655/5.18.1-xanmod1-1-skylake/initrd'

I do have /efi/loader/entries, but my kernels and initramfs are located directly in /boot, which is supposed to be supported by the script. I also have correct /lib/modules//initrd file. So the script doesn't even try to check if the path it suggests exists -- just picks one which "fits best" and doesn't try any other in case of failure.

Distribution used Arch Linux, dracut 056, systemd 251.2.

To Reproduce

1. Create empty /efi/loader/entries when booting not from /efi (e.g. /boot).
2. Shutdown / reboot / manually run dracut-initramfs-restore.

Expected behavior I expect dracut to successfully unpack initrd from either /boot or /lib/modules, I mean, in general to try different locations as environments can be very different.

Additional context Full log of manual run:

	perhaps it is corrupted?  *Possible* reason follows.

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.
