Please no, only one config file in /etc, copy that if needed. On SuSE
8.2 several services run chrooted already on demand, e.g. postfix and
named, and SuSEconfig/rcservice maintain the chroot env automatically.
Have a look at their mechanisms first, they seem pretty good.

If chroot.d/FILENAME contains a list of files needed in the chroot env
for each service, that would be a good general approach.

The tricky bit is to work out which files are needed. I tried with jail
and sshd once but couldn't get it working.

Yes.
