Hi,
from what I know you can't boot from raid5 since lilo nor grub were
capable of that last time I installed boot from raid.
A solution is to make a raid 1 /boot and boot from that. After that
the initrd can detect the raid-5 volume and can use it as a
rootfilesystem.
As for bootmanagers, grub is easier to work with but on some
quirky setups lilo might be your only choice.
However, Sarge having a
/boot raid 1
/ raid 5 setup
often doesn't require you to do anything outside the installer
menu to work.
Having an lvm on the root filesystem shouldn't make a difference, but
I suggest keeping /boot as simple as possible ( with the possible
exception of adding raid 1)
hope all goes well,
Andreas
