The grep in question in grub-mkconfig seems quite reasonable. This may well be a grep bug. Investigating.

Ok so this is a grub issue. Grub is incorrectly using grep to look for content in the file it has also connected to its output. Although grep is in silent mode this is still not permitted. Will spin a patch to clear that up.

The grep part is also bug 934269, now fixed. The lvs part: odd because grub2 doesn't invoke lvs itself, only via os-prober as far as I know, and os-prober is already supposed to set an environment variable to suppress those warnings ...

Apparently not fixed:

Sure enough, just as soon as I had posted the above, a new GRUB2 package entered the Precise mirror and it works:
