HowTo: Finit on Void Linux 3.4-3.6
|
||||
====================================
|
||||
|
||||
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 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 `/bin/busybox`:
|
||||
|
||||
void:~/finit# cd /sbin
|
||||
void:/sbin# rm init
|
||||
void:/sbin# ln -s finit init
|
||||
|
||||
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.
