Right.

[1] yes, reiserfs has an ioctl for lilo to call to ensure that the tail
of a kernel image or initrd isn't packed so lilo can use it. That is a
hack too.
Curious!
Another method would be to mark those "unmovable" files with a special
attribute (MsDos has it), so
that they are treated specially by the kernel and all tools that could touch
them.
By the way, one of those bugs is that grub doesn't handle reiserfs well, it
is broken (and reported).
(re s2disk, re booting on a stale filesystem: log has to re-played in memory,
and it does so in
minutes, not seconds.)
Yeah, I started working on a fix for that and probably have it lying
around somewhere.
