Okay - answering my own question and solved... It's a bug (or is that a
feature?).
In /etc/rc.d/jail line 647 it currently reads:
eval ${_setfib} jail ${_flags} -i ${_rootdir}
${_hostname} \
\"${_addrl}\" ${_exec_start} > ${_tmp_jail} 2>&1 \
</dev/null
And it should (IMHO) read:
eval ${_setfib} jail ${_flags} -n ${_jail} -i
${_rootdir} ${_hostname} \
\"${_addrl}\" ${_exec_start} > ${_tmp_jail} 2>&1 \
</dev/null
Once changed, everything works find and your jails are named as per the
rc.conf file definitions. Can anyone think of a reason for NOT fixing this?
