Title says it all. This is a fresh Fedora 17 system running on a Xen hypervisor. No idea why it won't start

What changes did you make to your /tmp directory? – Michael Hampton Oct 20 '12 at 3:59
/var/tmp is a symlink to /tmp and /tmp is mounted as: tmpfs on /tmp type tmpfs (rw,nosuid,nodev,relatime) – atx Oct 20 '12 at 4:03

Recent versions of Fedora/systemd include a new feature which generates random private directories in /tmp and /var/tmp for individual system services.

This means that there are things you should check:

  1. DO NOT symlink /var/tmp to /tmp or vice versa. These are treated separately and so you'll need to keep them separate.
  2. Ensure that both /var/tmp and /tmp have 1777 permissions.

If this doesn't resolve the problem, you may have found a bug, and should report it.

Wow that fixed it. Thanks! Weird how if I started it through /usr/sbin/httpd it would run fine, but not through systemd. – atx Oct 20 '12 at 4:18
To add to that, also do not mount /var/tmp as tmpfs, as its contents are normally expected to be preserved between reboots. – chutz Oct 20 '12 at 6:19
Also fixed a similar problem I had with rtkit on Debian Jessie. The answer might apply to all systems using systemd? – jopasserat Nov 23 '14 at 22:15
@jopasserat Most likely. Fedora contributes everything upstream, so that other distributions get it eventually. – Michael Hampton Nov 23 '14 at 22:21
