when bug #322969 got fixed it created one downside: nothing ever runs vgchange/lvchange --monitor y --poll y This manifests itself for example in palimpsest (gnome-disk-utility) where the VGs does not show up before you run "vgchange --monitor y --poll y" as root in a terminal. So currently it seems like gentoo/openrc would need an additional script for lvm running later during start up which starts this. This makes two out of three VGs appearers in palimpsest here.
Fixed in 2.02.67-r2, new init.d, lvm-monitoring based on upstream setup of monitoring.
