The initscripts take care of /proc, /proc/bus/usb, /sys, and /dev before any fscking goes on. > When I boot the system, I see that the "sys" VG gets activated and > fsck.ext3 is run for /dev/sys/ArchArch and /dev/sys/ArchUSR (messages > to the effect that such-and-such fragmentation exists shows and before > that, something like LVM [done]). BUT: I can't boot. Booting stops with: > > mount: special device /dev/mapper/sys-ArchArch does not exist > mount: special device /dev/sys/ArchUSR does not exist When fsck is done it does a mount -a, and your /dev is mounted over with a clean tmpfs, making your lvm volumes appear to vanish. > This shows, that both "paths" are not accessible; neither the /dev/sys/* > stuff (which on a Gentoo Linux installation contains symlinks to /dev/mapper), > nor the "proper" /dev/mapper path can be accessed. > > Any ideas about why that happens, and, more importantly, how to fix > that?
