Subject: Added Sign-off [PATCH] ip netns: Show error message if mkdir failed to create /var/run/netns
Date: Thu, 28 Aug 2014 16:56:03 +0300 [thread overview]
Message-ID: <1409234163-7567-1-git-send-email-vadim4j@gmail.com> (raw)
Currently if mkdir failed with "Permission denied" error then "mount --make-shared ..."
error message will be showed because /var/run/netns does not exist.
