Just thinking about it fast, NILFS2 is a filesystem that wraps around
the disk forever and LILO writes a bitmap of where the kernel image
is. So if NILFS moves the image then LILO is at lost and will load
some data which is not the kernel instead. A fast guess I would say
using LILO on NILFS is impossible by design.
