I don't see what there is to dislike. With this, the non-standard
behaviour of initramfs'es is nicely self contained within the initramfs
support code, and nothing else needs to know about it. There's nothing
to tweak, and it just works out of the box (tm), no matter what init
implementation or custom inittab is used.

You could argue that the shell overhead is a bit of a turn down, but
this is no worse than a S01mountall init script.
