 If you are using ext2/3/4 then you *should* use it to make a
filesystem on each partition (except for swap).  That way, if you
lose your notes about what is where, you can mount the filesystem
from a running system to see what it contains :)

 Wait for confidence ? 8)  The bootloader for an existing linux
system, even on a different disk, can have an entry for LFS added to
it.  If you have an existing system, there is no reason why the LFS
disk needs to be sda.

 You can use it.  Only one system can run at a time.

 It used to say ext2.  For a modern, large, disk (and where a kernel
which understands ext4 is alwayys going to be used), ext4 is better.
For /boot, ext3 or ext2 is probably more efficient - my own /boot [
about 100MB ] is large, so plenty of space for a journal.

 Until a couple of days ago, when I updated a few things on my
previous machine, I had forgotten that the version of e2fsprogs in
LFS-6.6 was slightly too old for ext4, which was why /home on that
box was still ext3 (it has an old 6.6 system available).  During the
boot, the filesystems all had to be fscked (last checked more than
200 days ago) : '/' on ext4 wizzed through, /home on ext3 took for
ever.

 Some people use different filesystems, and obviously they need to
install the tools for those.
