Bug#609004: cgroup-bin: cgred / cgrulesengd daemons not working because of missing kernel config

Package: cgroup-bin
Severity: grave
Justification: renders package unusable

The cgrulesengd daemon monitors processes started based on uid/gid, and those
that match the user filters get applied to the configured cgroup.

For the "monitor" part to work, the kernel must have CONFIG_PROC_EVENTS=y which
in turn requires CONFIG_CONNECTOR=y.

The default debian kernel has CONNECTOR=m, which means that PROC_EVENTS are not
available.

The result is that the "cgred" daemon in the cgroup-bin package does nothing
(never applies any rules) as it is unable to monitor for processes.



Debian Release: squeeze/sid
APT prefers testing
APT policy: (500, 'testing')
Architecture: amd64 (x86_64)

Kernel: Linux 2.6.32-5-amd64 (SMP w/2 CPU cores)
Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8)
Shell: /bin/sh linked to /bin/dash

It sounds like this only breaks a part of the functionality of the
cgroup-bin package, and the rest of the utilities work? On that basis,
downgrading the severity.

Cheers,
Julien
