I want to know if you can install grub to _one_ blockdevice backing
a device mapper device (softraid/lvm). You installed grub2 to both.

at this point no, but GPT/UEFI support will need to be added at some point.
to explain where my question is coming from:
find_usable_blockdevices() currently always excludes:
(1) disks which are partitioned (but their partitions are returned)
(2) blockdevices which are part of softraid/lvm devices
To give users more possibilities to install grub I'm adding an argument to this function to optionally also return devices in (1),
but while I'm at it, I started wondering about (2). I know some people install grub in some weird places,
so if this is technically possible and "okay" I might just as well allow this too.
