I'm not sure if option 1 is out of question (wait for other replies) but to recreate /var directory tree you can use mtree(8) on newly created partiton, something like: # /usr/sbin/mtree -du -p /var -f /etc/mtree/BSD.var.dist The downside of this (option 2) is you'll loose some important information about your system, /var/db/pkg comes first to my mind. If you don't have any backups try to recover anything you can first.
