For Samba filesystems, the Linux format is //host/share. The FreeBSD format is //user@host/share.

mount-dir

Directory where the filesystem will be mounted.

fs-type

Filesystem type keyword.

dump-freq

Integer indicating the frequency this filesystem should be backed up by the dump utility.

fsck-pass

Integer indicating the order fsck should check filesystems.

/etc/vfstab (Solaris)

block-dev char-dev mt-dir fs-type fsck-pass auto? opts

Similar syntax to the tradition fstab file, except:

  • Both block (for mounting) and character (for fcsk) special files are listed as the first two fields.
  • auto? is either yes or no, depending on whether the filesystem should be mounted automatically at boot time with mount -a.
  • The dump frequency field is not included.
