HowTo: Finit on Void Linux
==========================
HowTo use Finit to boot an [Void Linux][] system. It is assumed that
the user has already installed make, a compiler, C library header files,
and other tools needed to build a GNU configure based project.
To start with you need to first install [libuEv][] and [libite][]. They
default to install to `/usr/local`, but unlike Debian and Ubuntu based
distros, Void's `pkg-config` does not look for libraries and header
files there. So the `PKG_CONFIG_LIBDIR` environment variable must be
used, or change the install prefix to `/usr`.
The bundled [build.sh](build.sh) script can be used to configure and
build finit:
void:~# cd finit
void:~/finit# ./contrib/void/build.sh
Then run the [install.sh](install.sh) script to install all necessary
files, including the sample `finit.conf` and `finit.d/*.conf` files.
More on that below.
void:~/finit# ./contrib/void/install.sh
The install script is (supposed to be) non-destructive by default, you
have to answer *Yes* twice to set up Finit as the system default init.
Pay close attention to the last question:
*** Install Finit as the system default Init (y/N)?
If you answer `No`, simply by pressing enter, you can change the symlink
yourself later on, to point to `finit` instead of `runit`:
void:~/finit# cd /sbin
void:/sbin# rm init
void:/sbin# ln -s finit init
Another option is to change the Grub defaults, in `/etc/default/grub`:
#GRUB_CMDLINE_LINUX_DEFAULT="loglevel=4 slub_debug=P page_poison=1"
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=4 init=/sbin/finit"
Alternatively, you can simply modify the default Grub entry at boot, or
set up an alternative Grub entry to include:
linux /boot/vmlinuz-X.YY.Z ... init=/sbin/finit
If you modify a Grub configuration file, remember to run:
update-grub
Before rebooting, make sure to set up a [/etc/finit.conf](finit.conf),
and [/etc/finit.d/](finit.d/) for your services. Samples are included
in this directory. Notice the symlinks in `/etc/finit.d/`, which can be
managed by the operator at runtime using `initctl enable SERVICE`. You
can also use a standard [/etc/rc.local](rc.local) for one-shot tasks and
initialization like keyboard language etc.
