[PATCH v3 0/3] NFS basic junction support for nfs-utils

[Chuck Lever <chuck.lever@oracle.com>]

Still UNTESTED.

A while back I announced the deprecation of fedfs-utils. There were
a handful of components in fedfs-utils that we decided to keep. One
of those keepers was the "nfsref" command. (The other was autofs
support for /nfs4, which I hope Ian Kent is making progress on ;-)

This series introduces "nfsref" to nfs-utils, minus the overhead of
the LDAP / FedFS machinery, and it builds support for NFS basic
junctions into mountd, replacing the need to install a plug-in DLL
from fedfs-utils.

I didn't apply a lot of brain cells to this port, so it's perhaps a
little larger than it needs to be. Still, it achieves a completely
LDAP-free implementation that resides 100% in nfs-utils. I'm
interested in comments about the approach before I do more testing
and refinement.

./configure --enable-junction --enable-caps

is needed before building.


Changes since v2:
None.


Changes since RFC (v1):
Patch 2/3 in the original series added the libnfsjunct.so DLL to
nfs-utils. Series v2 instead replaces 2/3 with a patch that puts
support for junctions into mountd without the need for a DLL.
