Now we don't want /usr, or /proc, or /tmp, or /opt, or /boot, /lost+found,
/home, /var, but you want the directories.
I now vote for:
umask 022
tar -cf - /dev /bin /sbin /root /lib /etc | (cd /mnt/root_vg; tar -xvf -)
cd /mnt/root_vg; mkdir boot home mnt opt tmp usr var
Unless your /tmp is on the / filesystem.
Anyway, that should do it :)

It could also be done as:
find /dev -type f -o -type p -o -type b -o -type c
but it'd be easier to do:
cd /; find . -xdev -print | xargs tar -cf - /dev| (cd /mnt/root_vg; tar -xf -)

The 5 year plan:
In five years we'll make up another plan.
Or just re-use this one.
