I used cpio to copy my FC3 installation from one volume to another on the

properly and won't see wierd problems later when I upgrade to FC5. My
procdeure was to:

make a new LVM partition and filesystem the same size as original
(actually I resized a FC5t3 partition and filesystem and
did a "rm -rf /" on it)
boot from (FC5) rescue CD
mkdir /mnt/new
mount /dev/VolGroup00/LogVol02 /mnt/new
cd /mnt/sysimage
find . -depth -noleaf -xdev -size -102400K -print0 | cpio -dumpa0 --sparse /mnt/new
vi /mnt/new/fstab # edit to refer to LogVol02
# here would have been a good time to: touch /mnt/new/.autorelabel
umount /mnt/new
exit
boot original FC3
cream /boot/grub/grub.conf # add new stanza for same kernel new LVM
(gedit couldn't save the file)
boot new installation with kernel option "enforcing=0"
(eventually, after much horsing around with locking issues, etc.,
I decided that selinux was the problem and found the solution,
which was to setenforce 0, mount the new copy, touch its
/.autorelabel, unmount it, setenforce 1, and reboot as above.)

Some might say that I should have used dump and restore. Is there an
advantage over using cpio? I could have just used dd, but I tried cpio both
as a learning experience and in order to optimize the filesystem.

I think dump/restore is now supposed to take the extended attributes
that selinux needs. Other than that, 'cp -a' would be just as
good or 'tar -cf - ... | (cd target_path; tar -xpf - )'
