You can install a fresh install on top of the old install by using
`pacstrap`. I would boot up a live cd, move /etc to /etc_old, then
remove all other top levels directories other than /home, and install
again with pacstrap. The pacman database was in /var so there's little
point in trying to reinstall the same packages, and it doesn't seem very
important anyway - you'll remember what you used when it's missing, and
it's trivial to install it again.
