Comment 5 for bug 427356

Robbie, in that case why are changes to initramfs-tools required to implement this? The initramfs hook itself should figure out whether to run - initramfs-tools can't know, when building the initramfs, whether a filesystem check will be required since that's decided at boot.

The encrypted fs use case can be detected at initramfs build time, but that's not the only use case.
