Bug Description
Binary package hint: mdadm
Proposed command: "mdadm --incremental --run /dev/mdX"
Initramfs must be able to start (selected) md devices in degraded mode (only the ones that contain the rootfs and swap/resume partition), if they didn't start after some time of udev hotplugging. Starting all arrays, that are not yet complete at that early stage, degraded is not acceptable.
Initramfs could use the old non-incremental commands,
( i.e. "mdadm --run /dev/mdX" is preferable to "mdadm --assemble --scan" to start only selected array degraded)
but the old commands break the support for "auto-read" mode set up and smooth inclusion of members that appear later on.
Alternatively to a new --incremental option, make the old commands compatible and also start degraded arrays in "auto-read" mode and incrementally extendable by default.
