>Environment:

	NFSv3 server on FreeBSD 2.2(not tested on FreeBSD-current)
	and NFSv3 client.

>Description:

	FreeBSD NFSv3 server has readonly file permission problem
	under xemacs and mule.

	I think this problem is from NFSv3 server file handle program.

	This problem is:
	    o a file is managemented by RCS and still checked in.
	    o If that file does not be checked out
		and is edited by emacs,
	    o We can edit it and write it to NFSv3 server.
	      There is no warning message.

	But I can't find out and fix it.

>How-To-Repeat:

1. create readonly file on NFS server
-r--r--r--  1 sanpei  yamamoto  1421 Oct 19 23:54 test

2. open test file by mule (also checked by xemacs)
% mule -nw test

3. then....

case A [no problem]
NFS server	Solaris 2.5.1 for Intel
NFS client	FreeBSD 2.2.x and nfsv3 mount

in minibuffer
``Note: file is write protected''
--
case B [no problem]
NFS server	FreeBSD 2.2.2-R
NFS client	FreeBSD 2.2.5-BETA and nfs**v2** mount

in minibuffer
``Note: file is write protected''
--
case C [problem]
NFS server	FreeBSD 2.2.2-R
NFS client	FreeBSD 2.2.5-BETA and nfs**v3** mount

open read/write mode and it can be editted and written by save-file.

	Sorry I have no idea to solve it.
