DESCRIPTION The file /etc/vfstab describes defaults for each file sys- tem. The information is stored in a table with the following column headings:
device device mount FS fsck mount mount to mount to fsck point type pass at boot options
The fields in the table are space-separated and show the resource name (device to mount), the raw device to fsck (device to fsck), the default mount directory (mount point), the name of the file system type (FS type), the number used by fsck to decide whether to check the file system automati- cally (fsck pass), whether the file system should be mounted automatically by mountall (mount at boot), and the file sys- tem mount options (mount options). (See respective mount file system man page below in SEE ALSO for mount options.) A '-' is used to indicate no entry in a field. This may be used when a field does not apply to the resource being mounted.
The getvfsent(3C) family of routines is used to read and write to /etc/vfstab.
/etc/vfstab can be used to specify swap areas. An entry so specified, (which can be a file or a device), will automati- cally be added as a swap area by the /sbin/swapadd script when the system boots. To specify a swap area, the device- to-mount field contains the name of the swap file or device, the FS-type is "swap", mount-at-boot is "no" and all other fields have no entry.

DESCRIPTION
The file /etc/vfstab describes defaults for each file sys-
tem. The information is stored in a table with the following
column headings:
device device mount FS fsck mount mount
to mount to fsck point type pass at boot options
The fields in the table are space-separated and show the
resource name (device to mount), the raw device to fsck
(device to fsck), the default mount directory (mount point),
the name of the file system type (FS type), the number used
by fsck to decide whether to check the file system automati-
cally (fsck pass), whether the file system should be mounted
automatically by mountall (mount at boot), and the file sys-
tem mount options (mount options). (See respective mount
file system man page below in SEE ALSO for mount options.) A
'-' is used to indicate no entry in a field. This may be
used when a field does not apply to the resource being
mounted.
The getvfsent(3C) family of routines is used to read and
write to /etc/vfstab.
/etc/vfstab can be used to specify swap areas. An entry so
specified, (which can be a file or a device), will automati-
cally be added as a swap area by the /sbin/swapadd script
when the system boots. To specify a swap area, the device-
to-mount field contains the name of the swap file or device,
the FS-type is "swap", mount-at-boot is "no" and all other
fields have no entry.
