This breaks virt-alignment-scan. Not sure why yet.

It happens because adding -s changes the exit code of parted, so a
previously hidden error is exposed, and that in turn breaks the
part-list command when used on a blank disk.
$ parted -m -s -- tests/guests/blank-disk.img unit b print
Error: /home/rjones/d/libguestfs/tests/guests/blank-disk.img: unrecognised disk label
BYT;
/home/rjones/d/libguestfs/tests/guests/blank-disk.img:104857600B:file:512:512:unknown::;
$ echo $?
1
$ parted -m -- tests/guests/blank-disk.img unit b print
WARNING: You are not superuser. Watch out for permissions.

This is why I hate parted.
Anyway, I will post a v2 patch with this problem fixed.
