root(7M)							      root(7M)

NAME    [Toc]    [Back]

     root, rroot, usr, rusr, swap, rswap - partition names

DESCRIPTION    [Toc]    [Back]

     root, rroot, usr, rusr, swap, and rswap are the device special files
     providing access to important partitions on the root disk drive of	a
     system.  These links are made by the MAKEDEV(1m) script, and map to fixed
     partitions, even if not used that way by local conventions.  Therefore it
     is	best not to change these links,	if you intend to use different
     partition layouts,	but rather to use the full device name (/dev/dsk/dks*)
     instead, particular in fstab(4).  The names beginning with	r are the raw
     (character) device	access;	the others are the block device	access,	which
     uses the kernel buffer system.

     The standard system drive partition allocation shipped by Silicon
     Graphics has root on partition 0 and swap on partition 1.	Partition 7 is
     the entire	usable portion of the disk (excluding the volume header) and
     is	normally used for option drives, rather	than the system	drive.
     Partition 8 is the	volume header (see vh(7M), prtvtoc(1M),	and
     dvhtool(1M)).  Partition 10 (vol) is the entire drive.

     The standard system with SCSI drives usually has /dev/root	linked to
     /dev/dsk/dks0d1s0,	/dev/swap linked to /dev/dsk/dks0d1s1, and (if / and
     /usr are separate filesystems, a usrroot partitioning), /dev/usr linked
     to	/dev/dsk/dks0d1s6.
