Don't worry, I thought of that :) Considering that I built 2.2.7
twelve days after my last 3.0 build:
for dir in / /var /usr ; do
find $dir -xdev -mtime 12 -print | xargs rm -rf
done
and a second make installworld just to be sure I hadn't removed
anything useful. Libraries were slightly hairier than that because
there were links in /usr/lib/compat that had to be removed, but
nothing too challenging. And of course, I rebuilt all my ports - which
wasn't much (bash2, less, lynx, ncftp2) since this is a scratch box.
/etc is a whole other story. From memory:
# cd /
# pax -rwpe etc /var/tmp
# rm -rf etc
# mkdir etc etc/kerberos etc/ppp etc/mtree (and possibly a few others)
# cd /var/tmp/etc
# cp *passwd *pwd* group /etc
# cd /usr/src/etc
# make distribution DESTDIR=/
# newaliases
# cd /var/tmp/etc
# cp *passwd *pwd* group hosts host.conf resolv.conf rc.conf.local fstab /etc
