With these tools, you get clean shutdown (i.e., services are guaranteed to be
stopped before their loggers, so no logs are lost) and supervised logging of
supervise's output (so if the
last-resort logger is killed, it can be restarted). svclean-conf is a
configuration package for svclean. These features are practically necessary
for running svscan as process 1, but are useful
even when svscan does not run as process 1. Ideally, equivalent features
would be included in a future version of daemontools, and this package would
This package is discussed on the prjware list. New releases are announced on the prjware-announce list.
svclean and svsclean-conf are devoid of warranty and are distributed under the GNU General Public License, version 2. But that doesn't mean it's necessarily a good idea for you to distribute modified versions. (That includes repackaging.) I'd like to know if you plan to do that.
Older versions are published for historical interest.
Upgrading svclean-conf is not necessarily a good idea, because you must remember to copy your old configuration. New versions are provided only for improvements in the build system.
After upgrading svclean, you must restart
svscan to put the new
version into use, which may involve rebooting.
To build svclean, you need Laurent Bercot's

svscanwith svclean's wrappers.
svclean-shutdownprogram permanently shuts down all services and loggers.
A replacement command for
svscan that integrates the
functionality of the wrappers. Possible extra features: reap zombies
immediately rather than every 5 seconds; scan
/service for new
services only when notified via a named pipe; have a global
"shutdown" state where
supervise will not be
restarted; make the
supervise command line configurable.
