Discoverable Partitions: Look inside RAID 1 arrays

[LunarLambda]

As I understand, the Discoverable Partitions Spec restricts itself to only looking for partitions/filesystems that fully live on the same disk/block device as the EFI System Partition being booted from, which precludes most forms of RAID as well as LVM from being supported.

A partition that is part of a RAID 1 array (via an md device) is for all intents and purposes still fully self-contained to the disk it is stored on and functional even if the array is temporarily offline.

Right now my system is required to fully specify rd.luks.name and root manually, because while the DPS supports LUKS devices and can automatically decrypt and mount them, it cannot do so if the LUKS device is part of a RAID 1 array.

Is it worth considering making a small extension to the spec to allow for RAID 1 setups, since they are largely transparent with respect to the structure of the system?
