Activate LVM volumes if needed
An update to the Debian lvm2 package removed a script in the initrd that would activate any LVs that are required to access the root volume. Due to this change, grml failed to find its live media when it was stored on an LVM volume.
Add an explicit activation of any LVs mentioned in the live-media
or
bootfrom
kernel arguments, so that the live media can be found again.
