[lxc-devel] /proc/kmsg in the container

Hi,
lxc creates a symlink from /dev/kmsg to /dev/console
but unfortunately syslogd (i.e. from inetutils) wants to read from 
/proc/kmsg.
This caused very nasty problems on the host so I had to disable klog 
part of inetutils-syslogd.
I would also prevent containers to read my kernel buffer ring (dmesg) 
and hang the host syslogd, there is a way to have such kind of isolation?

Regards
