Right, its only in a failure hook, and things like cryptsetup won't be run after that...
The initramfs boot mechanism is just not designed with the right event driven approach yet. Bug #488317

Not quite right. That debconf question was a rather bogus, unhelpfull an unnecessary implementation. Bug #539597

It is wrong to to use "mdadm --assemble --scan --run", because it will start *all* arrays that have not come up yet in initramfs stage. (They get desynced and need to be resynced) Bug #497186
