Create a cronjob on debuild so the LiveCD is rebuilt automatically

[jdreed]

Before we plug the LiveCD, I'd like to ensure there's a good process for keeping it up to date.

If I understand the process by which the Live CDs/DVDs get built, /home/debuild/live-builder/live-builder should be an auto-builder.

I still want to grab some of the logging, output redirection, and error notification pieces from the autodebathenificator before it starts running in a cron job.

We also need to deal with the permissions on /mit/debathena/live. Currently daemon.debuild has rlik, which isn't sufficient to update the SHA{1,512}SUMS{,.asc} files. Because the live-builder appends to the SHA{1,512}SUMS files and replaces the signatures, I'd like to give daemon.debuild rlidwk, but I could rework things to make it work with rlidk if for some reason we're uncomfortable giving debuild full-fledged write? Although I don't really understand that.

Ok - this is now committed to debathena/scripts/build-server, next to autodebathenify. It's configured to run every Monday morning on debuild.

This successfully ran this morning, so modulo the outstanding quota issues, this should be all set.
