William Hubbs 6f614cd3f3 Move deptree2dot to the support folder

Since deptree2dot and the perl requirement are completely optional, we
can move this tool to the support folder. This gives the user the option
of using it if they have perl installed, and means we do not have an
optional runtime dependency on perl.

Documentation for this tool has also been added to the support folder.

OpenRC README

OpenRC is a dependency-based init system that works with the system-provided init program, normally /sbin/init. Currently, it does not have an init program of its own.

Installation

OpenRC requires GNU make.

Once you have GNU Make installed, the default OpenRC installation can be executed using this command:

make install

Configuration

You may wish to configure the installation by passing one or more of the below arguments to the make command

PROGLDFLAGS=-static
LIBNAME=lib64
DESTDIR=/tmp/openrc-image
MKNET=no
MKPAM=pam
MKPREFIX=yes
MKPKGCONFIG=no
MKSELINUX=yes
MKSTATICLIBS=no
MKTERMCAP=ncurses
MKTERMCAP=termcap
PKG_PREFIX=/usr/pkg
LOCAL_PREFIX=/usr/local
PREFIX=/usr/local
BRANDING=\"Gentoo/$(uname -s)\"

Notes

We don't support building a static OpenRC with PAM.

You may need to use PROGLDFLAGS=-Wl,-Bstatic on glibc instead of just -static.

If you are building OpenRC for a Gentoo Prefix installation, add MKPREFIX=yes.

PKG_PREFIX should be set to where packages install to by default.

LOCAL_PREFIX should be set when to where user maintained packages are. Only set LOCAL_PREFIX if different from PKG_PREFIX.

PREFIX should be set when OpenRC is not installed to /.

If any of the following files exist then we do not overwrite them

/etc/devd.conf
/etc/rc
/etc/rc.shutdown
/etc/conf.d/*

rc and rc.shutdown are the hooks from the BSD init into OpenRC.

devd.conf is modified from FreeBSD to call /etc/rc.devd which is a generic hook into OpenRC.

inittab is the same, but for SysVInit as used by most Linux distributions. This can be found in the support folder.

Obviously, if you're installing this onto a system that does not use OpenRC by default then you may wish to backup the above listed files, remove them and then install so that the OS hooks into OpenRC.

init.d.misc is not installed by default as the scripts will need tweaking on a per distro basis. They are also non essential to the operation of the system.

Reporting Bugs

If you are using Gentoo Linux, bugs can be filed on their bugzilla under the gentoo hosted projects product and the openrc component [1]. Otherwise, you can report issues on our github [2].

Better yet, if you can contribute code, please feel free to submit pull requests [3].

IRC Channel

We have an official irc channel, #openrc on freenode, feel free to join us there.
