The output of `sh -x /etc/network/if-up.d/mountnfs' (see below) made it
clear that the lock directory `/var/run/network/mountnfs' was not removed
properly at some point (when it should have been). I manually removed
it, and the script works now. The new question now is, why wasn't the lock
directory removed properly?

As mentioned above, the problem doesn't seem to be the script not
working with mounting the nfs directory, but rather that somehow the
lock directory was not deleted when it should have been. Just in case
this might be useful, I am still pasting the content of my /etc/fstab
and /etc/network/interfaces below.

I won't be able to test if I can reproduce the problem (not deleting the
directory /var/run/network/mountnfs). Manual execution of the script
/etc/network/if-up.d/mountnfs now works perfectly. I will reboot the
system tomorrow when I get in my office and see if things will be
different at boot time (I doubt it).

The problem came up when I upgraded my entire unstable system a few days
ago and that is probably when that lock directory was left behind for
some reason.
