If a syslog message is received for the facility 

.Em kern ,

but is not received directly from the kernel via the

.Pa /dev/klog

device, then 

.Xr syslogd

silently translates the facility to 

.Em user .

In particular, this means that when sending kernel logging messages to 

a remote loghost, they will be processed as facility 

.Em user

on the remote system.

This also means it is not possible to inject 

.Em kern

messages using the

.Xr logger 1

or similar program.

.Pp

If the priority code maps to the facility

.Em kern ,

but the message is not received via the

.Pa /dev/klog

device, then 

.Nm

silently changes the facility code to 

.Em user .
