Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
cinit is a fast init system with dependency features and
|
||
|
|
profile support. It was orientated on the design off Richard Gooch's
|
||
|
|
need [0] and Felix von Leitner's minit[1]. Minit does not support real
|
||
|
|
dependencies (you don't know whether the service you depend on really
|
||
|
|
started) and the need concept is somehow slow (as seen in gentoo).
|
||
|
|
In addition, minit needs libowfat and dietlibc, which may not be found
|
||
|
|
on every Unix system.
|
||
|
|
|
||
|
|
cinit main features:
|
||
|
|
- portability: it should run on every Linux system (and it's quite easy
|
||
|
|
to port it to other Unices)
|
||
|
|
- true dependencies
|
||
|
|
- parallel execution
|
||
|
|
- highly customisable (see conf/*)
|
||
|
|
- profile support (specify what services to start depending on the profile)
|
||
|
|
|
||
|
|
|
||
|
|
Getting cinit
|
||
|
|
=============
|
||
|
|
|
||
|
|
This README is part of the source, so you should have it.
|
||
|
|
If not, goto the homepage [2] and download the tar archive
|
||
|
|
or get the lastest snapshot via monotone.
|
||
|
|
|
||
|
|
|
||
|
|
Pre-Configuring
|
||
|
|
===============
|
||
|
|
|
||
|
|
If you want to fine tune cinit parameters, add different path names,
|
||
|
|
change the DESTDIR, ... have a look at conf/*.
|
||
|
|
|
||
|
|
|
||
|
|
Installing
|
||
|
|
==========
|
||
|
|
|
||
|
|
You can install cinit parallel to any other init-system, it won't
|
||
|
|
kill other init's config nor /sbin/init, if it exists.
|
||
|
|
|
||
|
|
You only have to tell your kernel to execute /sbin/cinit instead
|
||
|
|
of /sbin/init.
|
||
|
|
|
||
|
|
Everybody do:
|
||
|
|
# make all install
|
||
|
|
|
||
|
|
This will create /sbin/cinit.
|
||
|
|
If /sbin/init does not exist, it will be linked to /sbin/cinit.
|
||
|
|
|
||
|
|
If it's the first time you operate with cinit, you can also do:
|
||
|
|
# make install-test
|
||
|
|
|
||
|
|
This will populate /etc/cinit with a testing configuration,
|
||
|
|
which is somehow minimalistic
|
||
|
|
(mounting root r/w, starting gettys, setting hostname).
|
||
|
|
|
||
|
|
Although this should work on most Linux systems, it's really
|
||
|
|
minimalistic. Please configure your cinit installation yourself,
|
||
|
|
see below how to do that.
|
||
|
|
|
||
|
|
After configuring you need to tell your kernel to boot cinit instead
|
||
|
|
of your current init system. How to do that depends on your system:
|
||
|
|
|
||
|
|
Linux/LILO and Linux/yaboot (ppc):
|
||
|
|
append="init=/sbin/cinit"
|
||
|
|
Linux/grub1 and Linux/grub2:
|
||
|
|
kernel <normal kernel specification> init=/sbin/cinit
|
||
|
|
|
||
|
|
|
||
|
|
Configuring
|
||
|
|
===========
|
||
|
|
|
||
|
|
You'll have to configure /etc/cinit and add your existing services.
|
||
|
|
|
||
|
|
Please read doc/configuring.cinit for details.
|
||
|
|
Please read doc/FAO if there are still questions open.
|
||
|
|
Please join #cLinux on irc.freenode.org if there are still questions open.
|
||
|
|
|
||
|
|
There can be found some (currently only one) testing examples
|
||
|
|
below samples/ (some I do use for testing, beware if you use it:
|
||
|
|
It loads the dvorak keymapping at startup!).
|
||
|
|
|
||
|
|
There are currently no tools to merge your existing init-system
|
||
|
|
to cinit (like sysvinit-merge, bsd-merge or minit-merge) available.
|
||
|
|
If someone cares and tries to do that, I would be happy to include
|
||
|
|
the script(s).
|
||
|
|
|
||
|
|
Additionally I would be thankful for tar-balls containing a complete
|
||
|
|
replacement of $your_unix_init.
