mdadm will do mirroring, and is easy and well know to maintain.

Not sure if one needs any of the other features on the boot volume.
Only thing EXT4 would not do is checksum / integrity check - what i 
guess is the reason it is not supported.

afaik, it is possible to install debian minimal on mdadm raid and then 
add the proxmox repositories afterwards.
