Paketti: cloud-initramfs-rescuevol (0.45ubuntu1)

boot off a rescue volume rather than root filesystem

This package adds functionality to an initramfs built by initramfs-tools. When installed the initramfs will check to see if any partitions with a label of 'RESCUE_VOL' are attached. If such a volume is attached, it will boot off that volume rather than the root volume.

This is useful in a cloud environment, when the user is able to attach and detach volumes to a running system, but has no other mechanism for interrupting of fixing a failed boot. It is analogous to inserting a rescue CD into a system to recover from failure.
