I believe that the current functionality is that /sbin/hotplug is the default.
I think that if there is one in initramfs, it'll get called as a usermode
helper, even before init has run. (If it needs /proc /sys or /dev, setting
it up properly is its problem, but not an insurmountable one.)

I remember discussion of this a while back, and that it was indeed
intentional. I dunno if anybody's actually tried it.
