[fedfs-utils] [PATCH 3/3] resolve-junction: Remove the resolve-junction command
Chuck Lever
chuck.lever at oracle.com
Thu Jan 12 08:33:23 PST 2012
Mountd now uses a junction plug-in to resolve junctions. The
resolve-junction command, which mountd forked to resolve a junction,
is therefore no longer needed.
