[systemd-devel] Systemd port on custom embedded linux

[Cristian Axenie]

Hi all!
Next a failing context for DBus daemon is described both when using
systemctl enable dbus.service to generate links in the specific
.target.wants dirs or by using the default unit configuration after building
systemd.

So, after enabling the dbus unit and booting the board I get :

    9.500000] Freeing init memory: 152K
[   10.010000] systemd[1]: systemd 8 running in system mode. (+PAM +LIBWRAP

localhost login:

I am able to login and when running ps :

  898 root       0:00 /sbin/udevd
 1134 root       0:00 //lib/systemd/systemd-cgroups-agent
/systemd-1/udev-retry
 1135 root       0:00 login -- root
 1137 root       0:00 //lib/systemd/systemd-cgroups-agent
/systemd-1/dbus.servi
 1138 root       0:00 [dbus-daemon]
 1139 root       0:00 //lib/systemd/systemd-cgroups-agent
/systemd-1/dbus.servi
 1140 root       0:00 -sh
 1153 root       0:00 ps

DBus daemon seems dead and when trying to use systemctl to list the units it
blocks, but when sending SIGINT it returns to command line.

When using the default units configuration in the filesystem the DBus daemon
doesn't start, even if I try to start connmand (just an example). If I try
to start it manually it works.

Any suggestions ?


Best !
