Hi!

Perhaps you might be interested: I've written a small patch agains lilo-21.7 so that it recognizes boot files on a /dev/mapper/* volume.

I attached the patch below, but you can also find it at
http://www.saout.de/misc/. I also uploaded my initrd, to boot from a root volume on LVM2 for newer 2.5 kernels, there if someone is interested. (the libc is optimized for athlon and it needs a 8 MB ram disk - see kernel configuration).

Cool, I especially like the fact that you haven't needed any nasty BMAP ioctls :)
