Hi,
it seems that there are many developers out there which have
misunderstood the term
if intended use `$null'
Normally the special system facility `$null' should only be
used if the you really want an empty Required-Stop and/or
Should-Stop tag. In other words the most developers may
*not* want to use `$null'.
E.g. if in Required-Start the system facility `$user_fs' is
found then it is a bug to use `$null' in Required-Stop case.
The same holds true for Should-Start and Should-Stop.
Most users want to use for Required-Stop the same system
facilities and other provides as found in Required-Start.
The same holds true for Should-Stop.
There are some cases in which `$null' makes sense, e.g.
if in the Start case provides are used which simply do
nothing in stop case.
