Did give them a try - the pkg command referred to returned
Code:
pkg: Repository local missing. 'pkg update' required
pkg: Repository local load error: access repo file(/var/db/pkg/repo-local.sqlite) failed: No such file or directory
pkg: file:///usr/ports/packages/meta.txz: No such file or directory
pkg: file:///usr/ports/packages/packagesite.txz: No such file or directory
I updated the config for pkg in (what I believed was) the iocage and have now b0rked my FreeNAS box.
Time for a re-install of the base OS disk (data is on a separate ZVol) and then will attempt TarSnap in a VM on a separate server (local CPU does not support bhyve)
Not terribly impressed with the plugin and need to understand more before attempting again
