I agree.

I do not think this is a very good approach for this use case.

Making it an rc.conf option, enables the following tasks as a one-liner
change:
 - Enabling/Disabling skeleton jail (how will the system perform if I
have the template directories read-only?);
 - Switching template root (what will happen if switch from 7.1 userland
to 7.2 userland?);
 - Change mount points within all jails.

I do admit that all these can be done with scripts though.

Cheers,
