+s6-rc is a service manager for s6-based systems, i.e. a suite of
+programs that can start and stop services, both long-running daemons and
+one-time initialization scripts, in the proper order according to a
+dependency tree. It ensures that long-running daemons are supervised by
+the s6 infrastructure, and that one-time scripts are also run in a
+controlled environment.
 
 NOTE:
+s6-rc needs "live directory" where it puts some internal files that are
+needed at run-time. Default is /run/s6-rc. The default can be changed to
+other directory by passing LIVE_DIR=/path/to/directory environment
+variable to the SlackBuild script like below:
+
+    LIVE_DIR=/path/to/directory ./s6-rc.SlackBuild
+
+Make sure /path/to/directory is readable and writable by s6-rc or it
+will not work correctly. Using a RAM filesystem as the live directory is
+preferred.

 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:
