NAME

vfstab- Table of file system defaults

DESCRIPTION

The file /etc/vfstab describes defaults for each file system. 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 automatically (fsck pass), whether the file system should be mounted automatically by mountall (mount at boot), and the file system 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 may be used to specify swap areas. An entry so specified, (which can be a file or a device), will automatically 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.

Mount-time security attributes for a file system specified in the vfstab file can be specified with the -o or -S option on the mount(1M) command line or in an entry created for the file system in the vfstab_adjunct(4) file. See the DESCRIPTION sections in the mount and the vfstab_adjunct man pages for more about specifying security attributes. The vfstab file should not be edited directly; instead, it should be edited using the Set Mount Points action, which maintains the proper user, group, sensitivity label, and file permissions for the file and audits all changes. The Set Mount Points action resides in the System_Admin folder available in the Application Manager folder in the Front Panel. By default, the administrator (admin) role has the Set Mount Points action in the File System Management execution profile.

SUMMARY OF TRUSTED SOLARIS CHANGES

Two new pairs of security-relevant mount options devices|nodevices, and priv|nopriv can be specified in the vfstab file for filesystems that support them as filesystem-specific options: mount_hsfs(1M), mount_nfs(1M), and mount_ufs(1M). Mount-time security attributes can be specified for file systems whose objects do not have any attributes (such as user and group IDs) and for file systems that do not have the Trusted Solaris extended security attributes (such as sensitivity labels). Trusted Solaris security policy applies when mounting. The vfstab file should be edited by using the Set Mount Points action.
