I’ve been meaning to try
iocage on FreeBSD, but Dirk Engling and the team have done such a good job with
ezjail, I keep using it for everything. But I was reminded of an issue when using ezjail on standard zroot installs.
FreeBSD instances on OrionVM are installed into a zroot ZFS pool by default. I would know, I built them! You can live-attach a second disk and use that for your jails, but on a whim I decided to use my existing zroot. But in doing so, I had this come up:
# zfs create zroot/jails # ezjail-admin install -r 12.0-RELEASE ==> base.txz 147 MB 844 kBps 02m58s ==> tar: could not chdir to '/usr/jails/fulljail' ==> Error: Package install script for base failed.
There are two solutions. The easiest is to create it where it’s expected to find it by default:
# zfs create zroot/usr/jails
Or create as normal, but set the mountpoint:
# zfs create -o mountpoint=/usr/jails zroot/jails
And now new jail creates worked.
