First of all, please use the newest release (which is systemd-222). Secondly, please make sure you build systemd compatible to the needs of your distribution. This usually means copying the script from the systemd-build-script of upstream. We cannot support random systemd builds combined with existing distributions.

What exactly is the reason you build systemd by yourself? If you need local modifications, please use the build-tools of your distribution, which usually allows patches on packages before building them.

[zonque]

For instance, building for Ubuntu requires you to pass --enable-split-usr --with-rootprefix=/ during ./configure. @mbiebl and @martinpitt are the experts for systemd on Debian/Ubuntu around here :)

[martinpitt]

Sorry, not "d-bus". Ubuntu 14.04 does not use systemd, you can't use it there yet. The first Ubuntu release where systemd is officially supported is 15.04, and it barely works on 14.10.

Even if we use Ubuntu 15.04 This issue is the same @martinpitt i face it when i was trying to enable some of the services in one of the docker containers

the same on gentoo, with docker and after the mount -o bind of /dev, /proc, /sys in a dir for chroot

solution:with -rm optiion such as
docker run -ti -v /sys/fs/cgroup:/sys/fs/cgroup:ro --privileged -d -p 18002:18002 -p 1127:1127 -p 2222:22 --rm --ip 172.20.0.3 --net smbridge -h SmServer --shm-size=36G --name secom secom:v1

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
25 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
