It's already there. Guido once implemented incremental updates to the password database if only a single user's entry has been changed.

Nobody thought of this change when assembling the release notes for 2.2, not even the author. ;-) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
