and when entering the jail:

kern.osrelease: 12.0-CURRENT
kern.osreldate: 1200022
kern.disallow_high_osrel: 0

I have found some solutions for these already using "bare jails" so I'll send a PR in due course to fix this.

• ensure osrelease = "11.0-RELEASE-p8"; osreldate = 1100122; are transferred from template into jail
• use pkg -o ABI=${ABI} to ensure compatible packages are deployed

Is this still an issue? Any chance you could check wether it is related (and fixed in) to https://github.com/bartekrutkowski/iocell/pull/26 ?
