you're correct, "ROOT=$NEWROOT" is added to /conf/param.conf for every
device from /conf/conf.d/cryptroot. that means that it even happens for
resume devices.

i prepared a package which hopefully fixes this issue. it adds a flag
'rootdev' to /conf/conf.d/cryptroot for the real root device at
initramfs creation time. in the initramfs, cryptroot script checks for
that 'rootdev' flag before adding "ROOT=$NEWROOT" to /conf/param.conf.

that way the new introduced bug should be fixed while the lilo bug
remains fixed as well.

could you give the new package a try before I actually upload it to
debian/unstable? (everyone who commented on the bugreport is Cc'ed)

you can find the package (i386 and amd64) at:
