Installation guide

Each line contains an entry and the information is separated either by tabs
or spaces. An /etc/fstab file entry has the following information:
1 Specifies the block special device or remote file system to be mounted.
For UFS, the special file name is the block special file name, not the
character special file name.
2 Specifies the mount point for the file system or remote directory (for
example, /usr/man)orswap
n for a swap partition.
3 Specifies the type of file system, as follows:
cdfs
Specifies an ISO 9600 or HS formatted (CD−ROM) file system.
nfs
Specifies NFS.
procfs
Specifies a /proc file system, which is used for debugging.
ufs
Specifies a UFS file system or a swap partition.
advfs
Specifies an AdvFS file system.
4 Describes the mount options associated with the partition. You can
specify a list of options separated by commas. Usually, you specify the
mount type and any additional options appropriate to the file system
type, as follows:
ro
Specifies that the file system is mounted with read-only
access.
rw
Specifies that the file system is mounted with read-write
access.
sw
Specifies that the partition is used as swap space.
rq
Specifies that the file system is mounted with read-write
access and quotas imposed.
userquota
groupquota
Specifies that the file system is automatically processed by
the quotacheck command and that disk quotas are
enabled with the quotaon command.
By default, user and group quotas for a file system are
contained in the quota.user and quota.group files,
which are located in the directory specified by the mount
point. For example, the quotas for the file system on which
/usr is mounted are located in the /usr directory. You also
can specify another file name and location. For example:
userquota=/var/quotas/tmp.user
xx
Specifies that the file system entry should be ignored.
5 Used by the dump command to determine which UFS file systems
should be backed up. If you specify the value 1, the file system is
backed up. If you do not specify a value or if you specify 0 (zero), the
file system is not backed up.
