[Bug 911225] Re: grub-update: bad 'grep' and 'lvs' invocations

[Andy Whitcroft]

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.
