I’m sitting in the The Warden – FreeBSD and Linux Jail Management talk at EuroBSDCon 2012. He has mentioned two things, so far, that give me ideas. Evil ideas.

  1. Put each jail in a different ZFS data set – this may be useful for my jails running Bacula regression testing
  2. Schedule cron jobs to do snapshots on a regular basis – useful for snapshots, which I’m not really using at all

And he’s only 23 minutes into his talk…
