Recently I updated 23031107 to 20231108 on two laptops running legacy boot.

Both hang some time at console plymouth stuff. dracut then comes up with the
inability to find /dev/system/root.

It ends up in the dracut emergency shell. 

in the shell, lvm pvscan will report no physical volumes.

It also happens on a virtual machine. (also not UEFI).

If I try to recover with an usb stick, no partitions are shown. If I show
"all", 
the installed system is being identified als unknown, architecture unknown.
(and yes it's a 64 bit TW stick).

I could not recover them anymore. Also, on one of the laptops, grub does not
show windosws anmore, the other does. 

I luckily have a snapshot on my work vm so I can revert back.


The following packages are updated when this happens.

I tried  by mounting in rescue, created a new grub.cfg where osprober does not
show windows anymore. The interesting part is that dracut -f will as last line
shows "adding boot menu entry for UEFI firmware settings" 

Basically I will end up in reinstalling windows and linux on both laptops. 
(in legacy boot)

If needed, I can install the non-kernel parts and see what package eventualy
triggers this.
