Porting systemd To New Distributions
|
|
|
|
HOWTO:
|
|
You need to make the follow changes to adapt systemd to your
|
|
distribution:
|
|
|
|
1) Find the right configure parameters for:
|
|
|
|
--with-rootprefix=
|
|
--with-sysvinit-path=
|
|
--with-sysvrcnd-path=
|
|
--with-rc-local-script-path-start=
|
|
--with-rc-local-script-path-stop=
|
|
--with-kbd-loadkeys=
|
|
--with-kbd-setfont=
|
|
--with-tty-gid=
|
|
--with-ntp-servers=
|
|
--with-support-url=
|
|
|
|
2) Try it out. Play around (as an ordinary user) with
|
|
'/usr/lib/systemd/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
|
|
|
|
NTP POOL:
|
|
|
|
By default, timesyncd uses the Google NTP servers
|
|
time[1-4].google.com. They serve time that is not standards
|
|
compliant, and can be up to .5s off. Google does not
|
|
officially support these servers for the broader
|
|
audience. Distributions and vendors really should not ship
|
|
OSes or devices with these NTP servers configured. Instead,
|
|
please register your own vendor pool at ntp.org and make it
|
|
the built-in default by passing --with-ntp-servers= to
|
|
configure. Registering vendor pools is free:
|
|
|
|
http://www.pool.ntp.org/en/vendors.html
|
|
|
|
Again, if you ship your software or device with the default
|
|
NTP servers, then you will get served wrong time, and will
|
|
rely on services that might not be supported for long.
|
|
|
|
PAM:
|
|
The default PAM config shipped by systemd is really bare bones.
|
|
It does not include many modules your distro might want to enable
|
|
to provide a more seamless experience. For example, limits set in
|
|
/etc/security/limits.conf will not be read unless you load pam_limits.
|
|
Make sure you add modules your distro expects from user services.
|
|
|
|
Pass --with-pamconfdir=no to ./configure to avoid installing this file
|
|
and instead install your own.
|
|
|
|
CONTRIBUTING UPSTREAM:
|
|
|
|
We generally do no longer accept distribution-specific
|
|
patches to systemd upstream. If you have to make changes to
|
|
systemd's source code to make it work on your distribution,
|
|
unless your code is generic enough to be generally useful, we
|
|
are unlikely to merge it. Please always consider adopting the
|
|
upstream defaults. If that is not possible, please maintain
|
|
the relevant patches downstream.
|
|
|
|
Thank you for understanding.
