Adding

Comment 1 Michal Schmidt 2010-08-26 13:41:00 UTC

Which kernel version do you boot?

Comment 2 Brendan Jones 2010-08-26 14:12:03 UTC

2.6.35-3 although this has been recompiled with debugging off to get the nvidia 256.44 driver to work

Comment 3 Michal Schmidt 2010-08-26 14:17:24 UTC

That's why systemd has "Requires: kernel >= 2.6.35.2-9.fc14" - this kernel version added a patch to create /sys/fs/cgroup.

If you're using your own built kernel, you'll have to make sure you have that patch applied.

Comment 4 Brendan Jones 2010-08-26 14:56:26 UTC

Has 2.6.35.2-9 been built with debugging flags nit set (as fc13) or will that come later?

thanks

Comment 5 Michal Schmidt 2010-08-26 15:13:19 UTC

Fedora kernels on Branched (F-14) are still built with debugging enabled. http://fedoraproject.org/wiki/KernelDebugStrategy

Comment 6 Bill Nottingham 2010-08-26 16:05:39 UTC

If systemd wants to ensure a correct match with the running kernel, it could have Conflicts: kernel < 2.6.35.2-9.fc14

instead of the Requires.

Comment 7 Brendan Jones 2010-08-27 08:55:59 UTC

Have successfully rebuilt the 2.6.35.2-9 kernel with debugging off using systemd 8.1. Thanks for the heads up and quick response.
