[vdr] Request - an additional exit code

[Darren Salt]

I demand that Patrick Gleichmann may or may not have written...

Make at least N attempts to start vdr and record the start time for each of
the last N attempts. Once N attempts have been made, if the oldest of these
is too recent, stop trying to restart it.

My runvdr does this (see .sig; you want vdr_1.3.44-2.diff.gz).

If you want to do this in shell then something like the following (untested)
should be adequate:

  #! /bin/ash

  # ...

  START_1=
  START_2=
  START_3=
  START_4=
  START_5=

  while :; do
    START_1="$START_2"
    START_2="$START_3"
    START_3="$START_4"
    START_4="$START_5"
    START_5="`date +"%s"`"

    # run vdr here

    NOW="`date +"%s"`"
    test $(($NOW - $START_1)) -lt 60 && break
  done
