The pacman database was in /var so there's little point in trying to reinstall the same packages
What about software updates, security fixes, etc? ;-)
What is the less pain method to get it again up and running? The problem I
see are pacman list of installed packages?
Although you don't know what packaged you had (/var lost), you may use
/usr/bin/pkgfile to determine what package a file belongs to, e.g.
% pkgfile /usr/lib/liblink-grammar.so
extra/link-grammar
Run this across all the files in /usr, /etc and others, and you have a
list of the packages that need to be installed again.
Note: you need pkgfile, which means you need it from pacman, which means
you need to pacstrap. Daniel wrote how to do it.
