Default Bug#620421: nfs-kernel-server: init script depends on non-existent ‘/dev/tcp/’

Package: nfs-kernel-server
Version: 1:1.2.2-5
Severity: important
Tags: patch

The ‘/etc/init.d/nfs-kernel-server’ script has a new dependency on a
non-existent directory:

# See if portmap or rpcbind are running
(cat </dev/null >/dev/tcp/localhost/111) 2>/dev/null
if [ $RET != 0 ]; then
log_warning_msg "Not starting: portmap daemon is not running"
exit 0

This results in the script failing, with “Not starting: portmap daemon
is not running”.

That's nothing to do with the portmapper service. It's because there is
no such directory ‘/dev/tcp/’ on this machine:

$ ls /dev/tcp/
ls: cannot access /dev/tcp/: No such file or directory

To check for the portmapper service, the ‘rpcinfo(1)’ tool is provided.
Using that program, we can see that the service is running on this

$ rpcinfo -t localhost portmapper
program 100000 version 2 ready and waiting

The following patch uses this test, which works in current “Wheezy”.
