Binary package hint: mdadm
Initramfs has to start (selected) md devices in degraded mode. (The ones that contain the rootfs and swap/resume partition, if they didn't start after some time of udev hotplugging.)
It seems to be preferable to use --incremental not only in the udev rules but also in the boot scripts, because is said to support "auto-read" mode for smoth inclusion of members that appear later on.
But the boot script should only start selected arrays, i.e. the one containing the rootfs not all incomplete ones.
So where "mdadm --run /dev/mdX" is preferable to "mdadm --assemble --scan" (only start selected array degraded),
something like: "mdadm --incremental --run /dev/mdX" or to start all arrays in "auto-read" mode by default might be preferable to both.
