+### argv now contains the arguments of the kernel command line that are

+### This is done only once at boot time.
+### Ideally, this phase should just initialize the service manager.

+### If your services are managed by s6-rc:

+s6-rc-init -c /etc/s6/db/current /run/service

+### 2. Starting the wanted set of services
+### This is also called every time you change runlevels with telinit.
+### (edit the location to suit your installation)
+### By default, $rl is the string "default", unless you changed it
+### via the -D option to s6-linux-init-maker.
+### Numeric arguments from 1 to 5 on the kernel command line will
+### override the default.

+
+### If this script is run in a container, then 1. and 2. above do not
+### apply and you should just call your CMD, if any, or let your
+### services run.
+### Something like this:
+
+# if test -z "$*" ; then return 0 ; fi
+# $@
+# echo $? > /run/s6-linux-init-container-results/exitcode
+# halt
