Perhaps something to send upstream,
https://savannah.nongnu.org/projects/sysvinit/ >?   Someone
recently showed up on the upstream mailing list and offered to update
upstream source. :)

Bug#719273: sysvinit-utils: /bin/pidof fails when there are stuck NFS mount points, preventing shutdown

[Daniel Povey]

Package: sysvinit-utils
Version: 2.88dsf-41
Severity: important
Tags: d-i upstream

Dear Maintainer,

This bug is basically the same as 
https://bugzilla.redhat.com/show_bug.cgi?id=138788   
which has been resolved in Red Hat.  Basically, the current version of pidof 
looks in /proc
for stuff that it doesn't really need to look for, which leads to an attempt to 
access files or
directories on broken NFS mount points (if they exist), whifch leads to a hang. 
 This
prevents normal shutdown of a machine with broken NFS mount points. The Red Hat 
people seem to have 
fixed this issue already.


*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?  We have a system with many NFS mounts, some 
of 
  which sometimes go down.
   * What exactly did you do (or not do) that was effective (or
 ineffective)?  No satisfactory resolution yet.
   * What was the outcome of this action?
   * What outcome did you expect instead?

*** End of the template - remove these lines ***
