+s6-linux-init is a set of minimalistic tools used to create a s6-based
+init system, including a /sbin/init binary, on a Linux kernel.
+
+The resulting architecture follows the Unix philosophy (one job -> one
+tool) as closely as possible, and is fully dedicated to the s6 way of
+managing a system:
+
+- s6-svscan runs as process 1 for the whole machine lifetime.
+- Every daemon is supervised.
+- No logs are ever lost.
+- Policy is entirely left to the user. Typically, any service manager
+  can be run on top of s6-linux-init.
+
+Nevertheless, the architecture is fully compliant with various empirical
+and historical specifications. For instance, it provides:
+
+- utmp management compatible with sysvinit,
+- runlevel management, with a configurable default, overridable from the
+  kernel command line,
+- sysvinit-like commands to shut the system down, including a shutdown
+  command that follows the LSB specification.
+
+Optional dependencies:
+nsss (https://skarnet.org/software/nsss/) (not available at SBo)
+utmps (https://skarnet.org/software/utmps/) (not available at SBo)
+
+NOTE:
+s6-linux-init has some skeleton files that will be used to build the
+complete s6-based init system. These files will be placed under
+/etc/s6-linux-init/skel by default. You can change this by passing
+SKEL_DIR=/path/to/directory environment variable to the SlackBuild
+script like below:
+
+    SKEL_DIR=/path/to/directory ./s6-linux-init.SlackBuild
+
+The init system created by s6-linux-init will need an early boot tmpfs
+in order to work properly. By default, s6-linux-init will assume that
+this initial tmpfs will be mounted on /run. You can change this by
+passing TMPFS_DIR=/path/to/directory to the script
+
+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
+to the script like below:
+
+    BUILD_SHARED=yes ./s6-linux-init.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-linux-init.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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
