NAME

       kfs - disk file system

SYNOPSIS

       disk/kfs [ -rc ] [ -b n ] [ -f file ] [ -n name ] [ -s ]

DESCRIPTION

       Kfs  is	a  local user-level file server for a Plan 9 terminal with a disk.  It maintains a hierarchical Plan 9 file system on the disk and
       offers 9P (see intro(5)) access to it.  Kfs begins by checking the file system for consistency, rebuilding the free  list,  and	placing  a
       file descriptor in /srv/name, where name is the service name (default kfs).  If the file system is inconsistent, the user is asked for per-
       mission to ream (q.v.)  the disk.  The file system is not checked if it is reamed.

       The options are

       b n    If the file system is reamed, use n byte blocks.	Larger blocks make the file system faster and less space efficient.  1024 and 4096
	      are good choices.  N must be a multiple of 512.

       c      Do not check the file system.

       f file Use file as the disk.  The default is /dev/sd0fs.

       n name Use kfs.name as the name of the service.

       r      Ream the file system, erasing all of the old data and adding all blocks to the free list.

       s      Post file descriptor zero in /srv/service and read and write protocol messages on file descriptor one.

EXAMPLES

       Create a file system with service name kfs.local and mount it on /n/kfs.

	      % kfs -rb4096 -nlocal
	      % mount -c /srv/kfs.local /n/kfs

FILES

       /dev/sd0fs
	      Default file holding blocks.

NAME

       dossrv, 9660srv, a:, b:, c:, eject - DOS and ISO9660 file systems

SYNOPSIS

       dossrv [ -v ] [ -s ] [ -f file ] [ service ]

       9660srv [ -v ] [ -s ] [ -f file ] [ service ]

       a:

       b:

       c:

       eject [ n ]

DESCRIPTION

       Dossrv  is a file server that interprets DOS file systems.  A single instance of dossrv can provide access to multiple DOS disks simultane-
       ously.

       Dossrv posts a file descriptor named service (default dos) in the /srv directory.  To access the DOS file system on  a  device,	use  mount
       with  the  spec	argument  (see bind(1)) the name of the file holding raw DOS file system, typically the disk.  If spec is undefined in the
       mount, dossrv will use file as the default name for the device holding the DOS system.

       Normally dossrv creates a pipe to act as the communications channel between itself and its clients.  The -s flag instructs  dossrv  to  use
       its  standard input and output instead.	The kernels use this if they are booting from a DOS disk.  This flag also prevents the creation of
       an explicit service file in /srv.

       The -v flag causes verbose output for debugging.

       The shell script a: contains

	      unmount /n/a: >[2] /dev/null
	      mount -c /srv/dos /n/a: /dev/fd0disk

       and is therefore a shorthand for mounting a floppy disk in drive A.  The scripts b: and c: are similar.

       9660srv is identical to dossrv in specification, except that it interprets ISO9660 CD-ROM file systems instead of DOS file systems.

       If the floppy drive has an ejection motor, eject will spit out the floppy from drive n, default 0.

EXAMPLE

       Mount a floppy disk with a DOS file system on it.

	      dossrv
	      a:
