Change in vdsm[master]: Add a chown implementation that looks up uid and gid
by Federico Simoncelli 19 May '14

19 May '14

Federico Simoncelli has uploaded a new change for review. Change subject: Add a chown implementation that looks up uid and gid ...................................................................... Add a chown implementation that looks up uid and gid We already have a case in vdsm (configNetwork) where we need to use a chown function that is capable to convert the owner and group names to uid and gid. Going forward this can be reused for the deployment utilities and to prepare the paths needed by vdsm (eg: /rhev and /var/run/vdsm).
