Porting systemd To New Distributions
|
|
|
|
HOWTO:
|
|
You need to make the follow changes to adapt systemd to your
|
|
distribution:
|
|
|
|
0) Make your distribution recognized via the autoconf checks
|
|
in configure.ac. Grep for the word "fedora" (case
|
|
insensitively) and you should be able to find the places where
|
|
you need to add/change things.
|
|
|
|
1) Patch src/hostname-setup.c so that systemd knows where to
|
|
read your host name from. You might also want to update
|
|
status_welcome() in util.c.
|
|
|
|
2) Check the unit files in units/ if they match your
|
|
distribution. Most likely you will have to make additions to
|
|
units/*.m4 and create a copy of units/fedora/ with changes for
|
|
your distribution.
|
|
|
|
3) Adjust Makefile.am to register the unit files you added in
|
|
step 2. Also you might need to update the m4 invocation in
|
|
Makefile.am. Grep for the word "fedora" (case insensitively)
|
|
and you should be able to find the places where you need to
|
|
add/change things.
|
|
|
|
4) Try it out. Play around with 'systemd --test --system' for
|
|
a test run of systemd without booting. This will read the unit
|
|
files and print the initial transaction it would execute
|
|
during boot-up. This will also inform you about ordering loops
|
|
and suchlike.
|
|
|
|
CONTRIBUTING UPSTREAM:
|
|
We are interested in merging your changes upstream, if they
|
|
are for a big, and well-known distribution. Unfortunately we
|
|
don't have the time and resources to maintain
|
|
distribution-specific patches for all distributions on the
|
|
planet, hence please do not send us patches that add systemd
|
|
support for non-mainstream or niche distributions.
|
|
|
|
Thank you for understanding.
|
|
|
|
BE CONSIDERATE:
|
|
We'd like to keep differences between the distributions
|
|
minimal. This both simplifies our maintenance work, as well
|
|
as it helps administrators to move from one distribution to
|
|
another.
|
|
|
|
Hence we'd like to ask you to keep your changes minimal, and
|
|
not rename any units without a very good reason (if you need a
|
|
particular name for compatibility reasons, consider using
|
|
alias names via symlinks). Before you make changes that change
|
|
semantics from upstream, please talk to us!
|
|
|
|
In SysV almost every distribution uses a different
|
|
nomenclature and different locations for the boot-up
|
|
scripts. We'd like to avoid chaos like that with systemd right
|
|
from the beginning. So please, be considerate!
