Most of us are using LFS without a distro now (of course, we started with
a distro, but didn't use it anymore since we built our Systems the way we
wanted to use it). About that "portable" point, I suggest to avoid the
usage of any optimization flags (unset CFLAGS CXXFLAGS), otherwise your
LFS may not run on every system.

It is actually possible to put the linux kernel on a floppy disk. you 
could even tell lilo to use /dev/fd0 as boot partition (so it wouldn't
boot w/o the disk) - be sure to make a copy :-)

Straightforward, I'd say. Help can be found on that mailinglist, on or even within the BLFS book. There are
informations about bootdisks around there :-)
