I had to reinstall slackware because i ran into problems with dmraid mixed with grub. something happened where grub couldn't see the kernel anymore and i couldn't figure out why. So I read up on how to do LVM and found out that you can use LVM to also stripe your drives. I didn't find AlienBob's doc on how to install Slack on LVM until after i had done it but the steps i took still accomplished the same thing.
So after i had installed, i was having trouble running lilo and having it write to the MBR. i ended up chroot /mnt, did a vgscan --mknodes, and had to sym link dm-0 to /dev/mapper/vg0-lvs0 (i think.. i wish i could remember and say for sure). i do remember having to symlink it though. Once i had done that, created initrd, edited lilo and it worked.
However, after now being able to boot i can't write lilo again. this is what i get.

Lilo actually complains more than what i'm showing you. i will restart and post some more. However i think what i'll show you is an easy fix and im pretty sure i need to add mdadm -As somewhere in my initrd but i don't know where.
