[Bug 968211] [NEW] NFS kernel server initscript contains errors

[Marios Makassikis]

Public bug reported:

1) The release of Ubuntu you are using
I checked on the ubuntu install I have here - 12.04 precise pangolin beta - but it's likely the
bug is present in older versions too.

2) The version of the package you are using
nfs-kernel-server:
    Installed:  1:1.2.5-3ubuntu1

3) What you expected to happen
I expected mountd to be started for NFSv3

4) What happened instead
mountd was started, but version 1 and 2 only -- according to rpcinfo -p

5) The fix
The rpcinfo binary is located in /usr/sbin rather than /usr/bin

$PREFIX/bin/rpcinfo -u localhost nfs 3 >/dev/null 2>&1 ||
RPCMOUNTDOPTS="$RPCMOUNTDOPTS --no-nfs-version 3"

Whereas it should be:

$PREFIX/sbin/rpcinfo -u localhost nfs 3 >/dev/null 2>&1 ||
RPCMOUNTDOPTS="$RPCMOUNTDOPTS --no-nfs-version 3"

6) Possible improvement

Perhaps it can be further improved to check if the nfs process listens on TCP
rather than UDP.

I'm thinking this should do the trick:

$PREFIX/sbin/rpcinfo -u localhost nfs 3 >/dev/null 2>&1 ||
$PREFIX/sbin/rpcinfo -p localhost nfs 3 >/dev/null 2>&1 ||
RPCMOUNTDOPTS="$RPCMOUNTDOPTS --no-nfs-version 3"

If nfs 3 doesn't listen at least on one protocol, then RPCMOUNTDOPTS is
modified accordingly.
