	+ This paper is a revision of Thompson's
	+ .I "The Plan 9 File Server" ,
	+ and describes the structure
	+ and the operation of the new 64-bit Plan 9 file servers.
	+ Some specifics apply to the 32-bit
	+ Plan 9 file server
	  Emelie,
	- but
	- the code is also the basis for
	+ which code is also the basis for
	  the user level file server
	  .CW kfs .
	+ .PP
	+ Collyer recently created a 64-bit version of
	+ Thompson's 32-bit file server, updating all file
	+ offsets, sizes and block numbers to 64 bits.
	+ In addition, triple- and quadruple-indirect
	+ blocks were implemented.
	+ File name components were extended from 27 to 55 bytes.
	+ Further work is planned, notably improved peripheral and protocol support.

	  but it has slowly come to terms with
	  its particular set of cranky computers
	  and devices.
	+ .PP
	+ The file server
	+ .I fs64
	+ runs a revision of Emelie's code
	+ with 64-bit file sizes, offsets and block numbers
	+ and indirect blocks from single to quadruple.
	+ Actually these are 63-bit values, since the type used is
	+ .I vlong
	+ (signed
	+ .I "long long"
	+ integer),
	+ but 63 bits should suffice for a little while.

	  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/2006/0218/plan9/sys/man/4/consolefs:204,221
	  % clog /mnt/consoles/fornax /sys/log/fornax &

	  .EE

	+ 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 .
