Subject: [PATCH] generator: customize: Add new StringTriplet for use by
--chown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The just added --chown option previously used StringPair, splitting
the argument as UID.GID:FILENAME. However this will not work if we
ever extend this with the ability to use user or group names, since
they may contain dot (but not colon). Add a new StringTriplet type
and split the argument string three ways. The new option becomes:
virt-customize ... --chown UID:GID:FILENAME
Include the following commit from the common submodule:
commit e70d89a58dae068be2e19c7c21558707261af96a

customize: Update generated files for --chown with StringTriplet
Updates: commit d8e48bff212f9b0558480ffedf8158157360d0d5
(cherry picked from commit c08032ebe2763f5e9ce5b14e003721475219d390)
