During reboot after an LVM/encrypted root install, the /init script in
the initrd fails to find the root device. /init is calculating the root
major/minor numbers using a hex value supplied by Lilo to the kernel
command line (the value turned out to be incorrect in my case), when we
can easily forget about whatever Lilo thinks the root device is and just
use the value of 'target' in /conf/conf.d/cryptroot, simplifying things
greatly.
I've done just that in the following patch. Using the param.conf
facility, I set $ROOT right after cryptsetup sets up the encrypted root.
The patch has been tested and works for me just fine. Note that a
separate patch will be necessary for the case of an _unencrypted_ LVM
root mount. I can send one along if you wish.
