was this supposed to be an answer to my question? it's really not clear what your point is.
you asked if <insert list of three examples> could be done, i stated i used one of them *right now* ... i was indirectly implying it could be done and offering it forth as a partial answer. of course, i meant grub could be independently/safely installed to each raw device _backing_ a softraid ...
I want to know if you can install grub to _one_ blockdevice backing a device mapper device (softraid/lvm). You installed grub2 to both.
unless we are talking about UEFI booting here, in which case the (required?) GPT layout sorta guarantees a place for bootloaders?
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. Dieter
