- Bugfixes.
- Changes to s6-svscan and s6-svscanctl: the list of commands
that can be sent to s6-svscan has been thoroughly cleaned up.
s6-svscan now scans and prunes on SIGHUP.
- Changes to s6-supervise and s6-svc: -X not supported anymore,
nosetsid not supported anymore. SIGHUP now properly closes
stdin/stdout to allow the service to naturally exit on EOF;
SIGQUIT semantics changed to immediately bail. SIGINT is now
trapped and forwarded to the service's process group.
- New binary: s6-svperms, implementing a split permissions
model. (By default, everything is the same as before.)
- New binary: s6-usertree-maker, creating service directories
for supervision trees managed by users.
s6 is a small suite of programs for UNIX, designed to allow process
supervision (a.k.a service supervision), in the line of daemontools and
runit, as well as various operations on processes and daemons. It is meant
to be a toolbox for low-level process and service administration, providing
different sets of independent tools that can be used within or without the
framework, and that can be assembled together to achieve powerful
functionality with a very small amount of code.
