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.
|
|
|
|
Examples of things you can do by assembling together several programs
|
|
provided by s6 - besides process supervision:
|
|
|
|
- syslogd functionality, using much less resources than the traditional
|
|
syslogd.
|
|
- Reliable service readiness notification, which is the basis for
|
|
service dependency management.
|
|
- Controlled privileged gain as with sudo, without using any suid
|
|
programs.
|
|
- The useful parts of socket activation without having to change
|
|
application code or link servers against any specific library, and
|
|
without having to switch to any specific init system.
|

|
NOTE:
|
|
Upstream recommends building skarnet.org softwares with static libraries
|
|
as most of skarnet.org softwares are small enough that using shared
|
|
libraries are generally not worth using. Therefore, by default, shared
|
|
libraries are not built and binaries are linked against the static
|
|
versions of the skarnet.org libraries.
|
|
|
|
If you want to also build the shared libraries, pass BUILD_SHARED=yes
|
|
environment variable to the SlackBuild script like below:
|
|
|
|
BUILD_SHARED=yes ./s6.SlackBuild
|
|
|
|
Similarly, to avoid building the static libraries, you can pass
|
|
BUILD_STATIC=no to the script. For example, to only build the shared
|
|
libraries and not the static ones, you can do something like:
|
|
|
|
BUILD_SHARED=yes BUILD_STATIC=no ./s6.SlackBuild
|
|
|
|
If you just want to build and use skarnet.org softwares, building only
|
|
the static libraries should be sufficient.
|
|
|
|
If you want the binaries to be linked against the shared versions of the
|
|
skarnet.org libraries, pass LINK_SHARED=yes to the script.
