nfs-utils and unfsd

nfs-utils and unfsd

[Chuck Lever]

There is a generic RPC server helper in nfs-utils called rpc_init().   
This API will need to be modified to support IPv6 in statd and mountd,  
at least.

However, there is a comment inside support/nfs/rpcmisc.c, where  
rpc_init() resides, that suggests that this interface is also used by  
unfsd.

Is it OK for me to modify nfs-utils' copy of this function, or is  
there any kind of ABI restriction between unfsd and nfs-utils?

I'd also like to point out that the block comment at the top of  
support/nfs/rpcmisc.c says:

   5  * This code is partially snarfed from rpcgen -s tcp -s udp,
   6  * partly written by Mark Shand, Donald Becker, and Rick
   7  * Sladkey. It was tweaked slightly by Olaf Kirch to be
   8  * usable by both unfsd and mountd.
   9  *
  10  * This software may be used for any purpose provided
  11  * the above copyright notice is retained.  It is supplied
  12  * as is, with no warranty expressed or implied.

The second paragraph refers to "the above copyright notice," but there  
is no copyright notice.

I don't see any problem... Is there even a supported/maintained version
of unfsd out there today? I did a quick google search and didn't find
anything but man pages... 

steved.

I found this ancient web page:

http://rpm.pbone.net/index.php3/stat/4/idpl/6572509/com/unfs3-0.9.20-1.el3.pp.i386.rpm.html

which suggests there is no binary dependency between unfsd and nfs- 
utils.

I ask because we have had some unfsd questions on the list in the past  
year, so I assumed it was something that was still supported by some  
distributions.

This is unfs3, which is a rewritten from scratch by Pascal Schmidt and so 
unrelated to unfsd.
