mnttab(4)

DESCRIPTION

mnttab resides in directory /etc and contains a table of devices mounted by the mount command (see mount(1M)). The file contains a line of information for each mounted filesystem which is structurally identical to the contents of /etc/fstab described by fstab(4).

There are a number of lines of the form:

consisting of entries similar to:

/etc/mnttab is accessed by programs that use getmntent() (see getmntent(3X)), It should never be manually edited, nor should setmnt ever be used to create invalid entries in /etc/mnttab (see setmnt(1M)).

mount_time contains the time the file system was mounted using mount. Its value is the number of seconds since the Epoch (00:00:00 Coordinated Universal Time, January 1, 1970 (see time(2).

mount and umount rewrite the mnttab file whenever a file system is mounted or unmounted if mnttab is found to be out of date with the mounted file system table maintained internally by the HP-UX kernel. syncer also updates mnttab if it is out of date (see syncer(1M).

WARNINGS

The table is provided only as a means for programs to return information about mounted file systems.

/etc/mnttab should never be manually edited. Any manual changes made to /etc/mnttab are overwritten without warning by syncer, mount, and umount.
