I do install FC4 from tar archive over the net. My personal Howto
(which is specific for our partition strategy is below).
>From my (limited) experience the following will work:
1. Partition the new system with same partitions (labels, not size)
as the system you are copying from.
2. With a live CD (or older system on the new machine), copy the
installed files to the new FSs (you must copy with tar, rsync
or similar tool that preserve all file attributes and does not
do dereferencing, if you use cp, use cp -a).
3. You should copy (create) /proc /dev but NOT there content.
4. Do grub install on this disk.
5. Fix the /boot/grub/grub.conf for the drive numbering on the
actual machine it will run on (if it is the only disk there
it is probably hd0).
My partition strategy is even simpler than yours: just / and swap,
so boot is always the same partition as the root.
I did install new OS on a spare partition by copying it and just
adding it to the grub.conf on the existing boot/grub directory.
Ehud.
Notes. Please remember - this is internal script, so some things are
specific to us (e.g. the partition sizes). The check for arg1 and
Step 5 (ulnx09-to-nn.sh) are administrative check/tool.
If you have only 1 or 2 machines to install use the script as a
check list / guide. It is not worth the trouble to adjust it.
