Yep.

There are a few new files in the build farm subversion repo.  

hostdb.pm contains the logic
admin.pl is the script run to add/remove/enquire about hosts - it simply
prompts to the terminal.  It generates the rsyncd.secrets and
web/hosts.list files after each edit.

fill_db.pl is run every 2 mins from cron, to add new builds as they are
found.

mail-dead-hosts.pl runs every day to mail hosts which have not reported
in for a week.  It will repeat this mail every week after.  The initial
run sent out a pile of mail, but this hopefully won't be repeated, once
the long-dead machines are weeded out.

If you have ssh access to the build account, you must be on the mail
alias for build too, as the admin script will send an e-mail out from
this account with the new machine's password.  All mails are also BCC'ed
to the build alias (we may make this alias a mailman list of it's own). 

Users are also automatically subscribed to the build-farmers mailing
list when they join (again by means of a mail from the script).

In short, to add/remove machines, ssh to the build account on samba.org,
cd master; ./admin.pl

I hope this helps.
