   1 Porting systemd To New Distributions
   2
   3 HOWTO:
   4         You need to make the follow changes to adapt systemd to your
   5         distribution:
   6
   7         1) Find the right configure parameters for:
   8
   9             --with-rootprefix=
  10             --with-sysvinit-path=
  11             --with-sysvrcnd-path=
  12             --with-rc-local-script-path-start=
  13             --with-rc-local-script-path-stop=
  14             --with-kbd-loadkeys=
  15             --with-kbd-setfont=
  16             --with-tty-gid=
  17             --with-ntp-servers=
  18
  19         2) Try it out. Play around (as an ordinary user) with
  20         '/usr/lib/systemd/systemd --test --system' for a test run
  21         of systemd without booting. This will read the unit files and
  22         print the initial transaction it would execute during boot-up.
  23         This will also inform you about ordering loops and suchlike
  24
  25 NTP POOL:
  26
  27         By default, timesyncd uses the Google NTP servers
  28         time[1-4].google.com. They serve time that is not standards
  29         compliant, and can be up to .5s off. Google does not
  30         officially support these servers for the broader
  31         audience. Distributions and vendors really should not ship
  32         OSes or devices with these NTP servers configured. Instead,
  33         please register your own vendor pool at ntp.org and make it
  34         the built-in default by passing --with-ntp-servers= to
  35         configure. Registering vendor pools is free:
  36
  37         http://www.pool.ntp.org/en/vendors.html
  38
  39         Again, if you ship your software or device with the default
  40         NTP servers, then you will get served wrong time, and will
  41         rely on services that might not be supported for long.

  43 CONTRIBUTING UPSTREAM:
  44
  45         We generally do no longer accept distribution-specific
  46         patches to systemd upstream. If you have to make changes to
  47         systemd's source code to make it work on your distribution,
  48         unless your code is generic enough to be generally useful, we
  49         are unlikely to merge it. Please always consider adopting the
  50         upstream defaults. If that is not possible, please maintain
  51         the relevant patches downstream.

  53         Thank you for understanding.
