--config option goes back years and years - not sure of the exact date, but
could probably tell with 'git bisect' if you wanted me to.
The above would not quite be sufficient. You would still have to change the
'volume_list' field in lvm.conf (and update the initrd).
What you are proposing would simplify things in that you would not need
different 'volume_list's on each machine - you could copy configs between
machines.
