[linux-lvm] howto avoid initializing a particular volume-group at boot time?

hi and best wishes for the new year!
Let me describe my scenario: I have a big volume group (let's say:
/dev/vgbig/lv[1-9]) with a lot of snapshots in it and not used very
often. Another volume group (/dev/vgsmall/lv[1-9]) contains data for
normal use.

Because of initializing /dev/vgbig/ at boot time the machine becomes
usable after about 12h (twelve!)

It would be ok if the machine would boot with /dev/vgsmall
initialized, would do it's normal duty and in an late initscript would
initialize /dev/vgbig/ (vgchange -ay /dev/vgbig/ ) It would be ok to
wait now, because i could do my normal work.

I thougt about a rule in /etc/lvm/lvm.conf, but i am not sure how to
write it.

Does anyone? Thanks in advance, tom
