I was trying to make systemd 212 run in lxc implementation of docker(on nixos linux distro), libcontainer. Well it crashes immidiately, without any log output or anything. This is backtrace from gdb: #0 0x00007ff44f7e3d10 in __pause_nocancel () from /nix/store/94n64qy99ja0vgbkf675nyk39g9b978n-glibc-2.19/lib/libpthread.so.0 #1 0x000000000048595d in freeze () #2 0x000000000049aa2e in main () What is funny is that i'm able to run it perfectly fine if PID>1 using --system flag. Just as an info, i'm running it from init shell script, which does exec(so replacing shell process with systemd process). I also reported this issue to docker https://github.com/dotcloud/docker/issues/6730
Docker/LXC are probably not setting up something properly that is necessary to log. Would be good to get an strace.
Please provide the console output of this, when you boot systemd with systemd.log_level=debug systemd.log_target=console on the container's PID 1 command line. Otherwise I cannot really tell you much....

Otherwise I cannot really tell you much.... Well i do that, but the problem is that systemd crashes immidiatelly and no debug output is printed out. I might be able to run it with debugging symbols and debug trace might be better, do you have any other suggestion? What's funny is that this is known problem in docker, but looks like no one else has bothered to fix it.
consider running systemd with "strace -D -o /tmp/foobar" or so, to see if any syscalls fail.
Anyway, this is nothing to fix in systemd really. The docker guys need to set up their execution environment right for systemd if they want to be able to run it in a docker container. How that's supposed to be done is well documented in http://www.freedesktop.org/wiki/Software/systemd/ContainerInterface/ Closing this bug now. Feel free to reopen if you have a specific issue where you think systemd is doing something wrong, that is not covered by the docs above.
