This is a recurring submission and includes corrections to various issue spotted. I guess I can just skip over reporting ubiquitous comma placement fixes… Highligts in this particular commit: - the "unsigned" type qualifier is completed to form a full type "unsigned int" - alphabetic -> lexicographic (that way we automatically define how numbers get sorted)

<para>Unit configuration files for services, sockets,

configuration options which define the process killing

parameters of spawned processes.</para>

<para>This man page lists the configuration options
|
|
shared by these four unit types. See
|
|
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|

configured with

<varname>ExecStop=</varname>). If set

killed. In this case only the stop

stop, but no process be killed

otherwise. Processes remaining alive

after stop are left in their control
