I formulated a workaround by writing a script that I can call from
cron. Basically along the lines of:
[ $# -ne 1 ] && echo "usage: $0 /path/to/wordlist.db" && exit 1
# Delete user tokens that are older than 7 days
/usr/local/bin/bogoutil -a 7 -m $DATABASE
# Rebuild the database to save disk space
/usr/local/bin/db4_dump $DATABASE > $DATABASE.data
/usr/local/bin/db4_load $DATABASE.new < $DATABASE.data
/bin/mv $DATABASE.new $DATABASE
I can feed it a list of databases (find -name is your friend) and it
conveniently snips as required.
It would be nice for there to be a bogofilter option that auto-expires
after X days, however.
