* * Improve init script: specifically manage salt configurations rather than arbitrary salt processes
Unfortunately SysV init scripts tend to rummage through PIDs filtering for
appropriate processes to manage. Unfortunately the filters are usually weak
and don't account for similar processes run by other users, PIDs of dead
processes being re-used for completely different executables, etc.. These
weaknesses can result in killing unrelated processes with potentially serious
results.
These improvements to the SysV init script is a complete rewrite with the
following improvements:
* Specifically manage individual salt configurations rather than looking for
salt minion-like processes.
* Obtain salt minion information from the salt configuration - use the
information to manage the specifically configured process.
* Drop all of the platform-specific helper functions that allow the
previously-mentioned weaknesses.
+ Unfortunately this means that the output information may not match the
specific platform (this could easily be corrected).
* Now can manage multiple salt processes started by different users
+ Unfortunately starts/stops/restarts as a group and is unable to manage
them both as a group or as individual processes (this could easily be
corrected)
The new initscript also allows various control variables to be overridden by
environment variables or through settings put in ``/etc/sysconf/salt`` or
``/etc/default/salt``.
:SALTMINION_DEBUG: Dump each line expansion before execution, output system
information on failure. Default: unset
:SALTMINION_BINDIR: Location of ``salt-minion``, ``salt-call`` and other
executables. Default: ``/usr/bin``
:SALTMINION_SYSCONFDIR: The parent directory for the ``salt`` configuration
directory and the ``sysconfig`` or ``default``
directory.
* Add lines that went missing in the rebase+squash
