	  An example of 2 consoles complete with console logging is:
	  .IP
	  .EX
	+ % cat /lib/ndb/consoledb
	+ group=sys
	+ 	uid=glenda
	+ console=bootes dev=/dev/eia0 gid=sys
	+ console=fornax dev=/dev/eia1 gid=sys
	  % aux/consolefs
	  % ls -p /mnt/consoles
	  bootes
	/n/sourcesdump/2006/0217/plan9/sys/man/4/consolefs:199,204 - 
	/n/sourcesdump/2006/0218/plan9/sys/man/4/consolefs:204,221
	  % clog /mnt/consoles/fornax /sys/log/fornax &
	  % clog /mnt/consoles/bootes /sys/log/bootes &
	  .EE
	+ .PP
	+ The console server's default name space must 
	+ mount the consoles for 
	+ .I C
	+ to import.
	+ This can be arranged by adding
	+ .IP
	+ .EX
	+ mount /srv/consoles /mnt/consoles
	+ .EE
	+ to
	+ .BR /lib/namespace.$sysname .
