[Bug 951925] [NEW] nfs-kernel-server init script calls non-existent /usr/bin/rpcinfo, failure disables NFSv3

[Neil Bertram]

Public bug reported:

The /etc/init.d/nfs-kernel-server script in Precise has a reference at
line 115 to $PREFIX/bin/rpcinfo:


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

Where $PREFIX is /usr, making the path /usr/bin/rpcinfo

Since this command doesn't exist, RPCMOUNTDOPTS always includes --no-
nfs-version 3, meaning you can never run with NFSv3 support.

In Precice, the rpcbind package provides the rpcinfo binary, but it's in
/usr/sbin/rpcinfo, not /usr/bin/rpcinfo. In Oneiric both rpcbind and
libc-bin provided rpcinfo binaries, with the latter being
/usr/bin/rpcinfo. It appears libc-bin no longer includes rpcinfo in
Precise.

Elsewhere in the same init script (eg. line 88) reference is made to
/usr/sbin/rpcinfo as well, so looks like it was just a patchy job
updating this init script at some point.

Symlinking /usr/sbin/rpcinfo into /usr/bin/rpcinfo fixed the problem for
me, but obviously the init script needs updating.

This is on a complete fresh install of Precise server beta1 with latest
packages from the repos.
