7.43, oops, yes ;) I will do, but it didn't look like that would help
since the new:

# LVM2 initialization
if [ -d /etc/lvm/ -a -x /sbin/lvm ]; then

stuff happens after the fsck /, and looks like it has to because it
needs a writable root filesystem.

(I played with mounting a tmpfs on /dev/mapper, doing the mkdmnod and
fscking the root device like that manually, but scripting that would
require mapping /dev/mainvg/rootfs to /dev/mapper/mainvg-rootfs, not
sure if that's a well-defined mapping)
