Identical jails with 1-2 unique directories?

[kha...@gmail.com]

Hi all,

I am trying to run multiple instances of single application times in different jails. Everything should be the same on every jail (same packages, /etc/passwd, etc). I do not want multiple copies of the application code, libraries, etc. To that end, I tentatively have narrowed it down to 1-2 directories being unique per jail and maybe /etc/rc.conf for the hostname and IP configuration.

Is there a way to have jails that are identical by default except for the aforementioned items?

Thanks!
