Everyone seems to talk about running through the normal installation
process, my approach is generally to clone an existing install. This won't
help much if you want to try new versions/distributions etc...

mount /dev/hda5 /mnt

rsync -rav -H --one-file-system / /mnt/

# repeat for all other filesystems you need
# e.g. If this was the source box and I needed to clone it, I
# would sync usr2 as well.

   Filesystem           1k-blocks      Used Available Use% Mounted on
   /dev/md0               5044064   4119988    667848  87% /
   /dev/md1             192958776  19148768 173810008  10% /usr2

e.g.
rsync -rav -H --one-file-system /usr2/ /mnt/usr2/

Note that tar will work fine too...

(cd / && tar --one-file-system -cf -) | (cd /mnt && tar -xvf -)

The filesystem locks stop you from copying /proc by accident.

then you can chroot into the new filesystem and it should work
fine... e.g.

chroot /mnt/


you can tweak whatever settings you need, e.g. /etc/fstab will be
required, and probably your network config.
