I have installed Disco, layout /usr on it's on LV, and at reboot same problem as describe in the impact section. Server stuck in trying to mount /usr due to lack of LVM activation.
At the initramfs prompt, I ran 'lvm vgchange -ay' to boot properly. I installed the disco-proposed package of lvm2[0], reboot the system and everything boot fine. The udev rule fix does the work correctly.
