Subject: mount: check options as well as fstype for network mounts
X-Git-Tag: v218~226
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=affc3d834347076e8616948978e70ed1fca84db4

mount: check options as well as fstype for network mounts

When creating a new mount unit after an event on /proc/self/mountinfo,
check the mount options as well as the fstype to determine if this is a
remote mount that requires network access.
