Comment 2 for bug 517773

For the record: With the current kernel it is sufficient to change $KLogPath to /proc/kmsg (in /etc/rsyslog.conf); it already does the right thing of starting as root, opening the fds, and dropping privs only afterwards (I get a fully working kern.log).

So the only thing we need to add there is the check if reading as user is allowed, and if it's not, to not drop privileges.
