Comment 21 for bug 251164

I believe the initramfs only sets up the rootfs, other partitions (/home) are set up afterwards. If I remeber correct cryptsetup is called by udev rules. In any case, that is the way it has to be, event driven, to catch on upon (/home) devices appearing without polling loops and sleep delays.

When I looked, I think bootwait, mdadm and cryptsetup where all looping and sleeping in initramfs independently in whatever course they get called. Therefore I suggested the watchdog timers I mentioned above and in the wiki.
