Clean up old pre 12 jails/warden

[Herman Eggink]

All,
I have upgraded my system for many years, currently on TrueNAS-12.0-U6. I currently only run fairly new jails all newly installed under 11.2+.
My system still has a jails folder with the following contents:

Code:

root@freenas:/mnt/Main/jails # ls -l
total 103
drwxr-xr-x   3 www   www     3 Jan 16  2014 .plugins
drwxr-xr-x   5 root  wheel   5 Jun  1  2015 .warden-files-cache
drwxr-xr-x  18 root  wheel  22 Dec 14  2014 .warden-template-pluginjail--x64
drwxr-xr-x  18 root  wheel  22 Nov 21  2016 .warden-template-pluginjail-10.3-x64
drwxr-xr-x  18 root  wheel  22 May 27  2018 .warden-template-pluginjail-11.0-x64
drwxr-xr-x  18 root  wheel  22 Jan 17  2014 .warden-template-pluginjail-9.2-RELEASE-x64
drwxr-xr-x  18 root  wheel  22 Mar 24  2014 .warden-template-pluginjail-9.2-x64
drwxr-xr-x  18 root  wheel  22 Aug  4  2015 .warden-template-pluginjail-9.3-x64
drwxr-xr-x  17 root  wheel  21 Jun 17  2017 .warden-template-standard_10_3
drwxr-xr-x  17 root  wheel  21 Jun  1  2015 .warden-template-standard--x64
drwxr-xr-x  17 root  wheel  21 Jan 14  2018 .warden-template-standard-11.0-x64
drwxr-xr-x  17 root  wheel  21 Sep  8  2015 .warden-template-standard-9.3-x64
drwxr-xr-x  17 root  wheel  23 Feb 27  2015 .warden-template-VirtualBox-4.3.12

Containing a gazillion files that I don't believe is being used as the oldest 'release' being used by any jail is 11.2-RELEASE-p7.

Can I just delete these?

Yep, those can be removed!

Excellent, thanks!
