[libvirt] [PATCH] Take Two - Fix domain restore for files on root-squash NFS.

I guess that line is okay to leave in the commit message.  If it had been
me, though, I would have left it out of the commit log, and just inserted
it between the --- and diffstat during 'git send-email --annotate' - it is
relevant to the thread that explains the updated commit and how it differs
from the first attempt, but it is not really related to the patch itself.
 After all, at the end of the day, the original version of this patch will
not be in libvirt.git, so the words "This version" no longer have any
context for comparison.  Likewise, a subject line of "[PATCHv2] Fix..." is
better than "[PATCH] Take Two - Fix...", since git am strips
"[PATCH...]" but not "Take Two".

ACK - you fixed everything I brought up, and the patch itself looks good.
