Bug#775583: New initramfs-tools boot script needed to activate VG needed only for /usr

[Ben Hutchings]

Package: lvm2
Version: 2.02.111-2
Severity: serious

initramfs-tools 0.117 added mounting of /usr from the initramfs.
Currently, if /usr is on a VG that is not also used by root or a
hibernation device, that VG is not activated and the user must
explicitly activate it through the emergency shell.

I believe it is necessary to add a new script stage to support
this.  I'll send a proposed script shortly.

Ben.
