Bug#814036: initramfs-tools: mdadm doesn't assemble disk

[Chris Boot]

Hi folks,

I think that this bug is a regression due to the fix for #784070, which
was fairly recently pushed to both unstable and *stable*. We have at
least one client server that got bitten by this and failed to boot.

I suspect the incremental assembly, which breaks booting from degraded
arrays, was sufficient to start arrays on block devices that take a bit
longer to show up than usual. With that now disabled, if the disks
haven't showed up by the time mdadm runs in local-top, you're screwed.

Adding "rootdelay=15" to the kernel command-line probably fixes this
(can't test as we can't just reboot this production server at will) but
this isn't a nice fix.

It seems like #714155 is also somehow related, but hasn't seen any
activity since July 2013.

HTH,
Chris
