No problem, thanks for replying to both mails.

Yeah chroots are needed, but I couldn't get it to work as I played with
mdraid 1 and 5 for testing grub on it.

#492897 is the cloned bug, for the wishlist request to support this.

See #475585
As I tried the whole mdraid stuff out I always had both forms mdN and md/N
As long as you have a /dev/mdN without / everything is fine for grub-probe

It won't work anyway with the super 1.X format.
grub-setup is able to detect this and warn about (see the message from Robert about this in this report)
But grub-probe doestn't use that code, it uses only the code real grub uses.

As I cloned the bug I wanted to leave it open for the case you've still problems with super 0.90.
But I leave it now to Robert if he wants to close it or retitle it to sth. like
"grub-probe fails to warn about unsupported super 1.X"

I looked a bit at the Code but using the one grub-setup is using isn't that easy in grub-probe,
because grub-probe has to care about LVM devices too.
