Description of problem: I can't get systemd to boot inside an LXC container. Version-Release number of selected component (if applicable): systemd-38-6.git9fa2f41.fc17.x86_64 How reproducible: Always Steps to Reproduce: 1. Install Rawhide in a disk image 2. Mount the root partition from the disk image on the (Fedora 16) host 3. In (Fedora 16) virt-manager, create an LXC VM pointing at that mounted root partition, and "install" it Actual results: [after a while, in the guest console] Welcome to emergency mode... Give root password for maintenance Expected results: Normal login prompt Additional info: I tried using the workarounds here: http://berrange.com/posts/2011/09/27/getting-started-with-lxc-using-libvirt/ and here: https://raw.github.com/gist/1142202/341dcda53059644bc48ec58cf7ec539ed782e06b/setup_lxc_rootfs_fedora15.sh but it still goes into emergency mode. I suspect I need to disable udev completely.
Can you boot your LXC tree with "systemd-nspawn"? Do you get any logging output when you boot like this? What if you add systemd.log_level=debug to the command line of init?
systemd-nspawn didn't work either. The problem was that step 1 (install onto disk image) had set up /etc/fstab with some partition UUIDs in it, and systemd couldn't find the disks mentioned in /etc/fstab when I tried to boot it in a container, because by that point, I had moved the root filesystem from the disk image to a directory in the host's /home (I did not mention that above, sorry). After I fixed this problem by emptying /etc/fstab, killed systemd, and retried systemd-nspawn again, it booted up. A clearer error message would have been nice. I had no clue that the problem was due to /etc/fstab. But basically it was my fault.
Hmm, there should have been some message that some device unit never became available. Can you paste the output that was generated? To improve what is printed I'd first like to see what is currently being printed for you.

It might be behaving differently now though than when I first reported this bug, because I've upgraded since then.
systemd-44-12.fc17 fixed many bugs related to containers. Are you still seeing the bug with this version?
We don't start udev in the container, hence this will necessarily fail to start. Please remove fstab in your container, as we do not support virtualized devices in the container.
