Hi,
I have recently configured my own kernel from pretty much from scratch and nearly everything went well. One thing that made issues however was consolekit.

After some investigating and comparing my config with some generic kernels, the issue turned out to be that I have deactivated CONFIG_AUDITSYSCALL.

The CONFIG_AUDITSYSCALL describtion states:

> Enable low-overhead system-call auditing infrastructure that can be used
> independently or with another kernel subsystem, such as SELinux.

Since I do not use SElinux I thought it was save to disable this feature.

IMO something like consolekit support should definately be mentioned in the describtion alongside with SElinux, considering that it is probably more frequently used than SElinux.
Otherwise it may be misleading.

Hope this gets fixed :)
