automatic
Automatically mounts a file system when the system is started. Unlike the true value, filesystems which are mounted with the automatic value are not mounted with the mount all command or unmounted with the unmount all command. By default, the '/', '/usr', '/var', and '/tmp' filesystems use the automatic value.
Still not clear with automatic. So how come it mounted and unmounted? I think automatic only uses for system and we should not touch. And other file systems is manipulated by us with true/false.

umount
UMOUNT(8) BSD System Manager's Manual UMOUNT(8)NAME
umount -- unmount filesystems
SYNOPSIS
umount [-fvFR] [-t fstypelist] special | node
umount -a [-fvF] [-h host] [-t fstypelist]
DESCRIPTION
The umount command calls the unmount(2) system call to remove a special device or the remote node (rhost:path) from the filesystem tree at
the point node. If either special or node are not provided, the appropriate information is taken from the fstab(5) file.
The options are as follows:
-a All the currently mounted filesystems except the root are unmounted.
-f The filesystem is forcibly unmounted. Active special devices continue to work, but all other files return errors if further accesses
are attempted. The root filesystem cannot be forcibly unmounted.
-F Fake the unmount; perform all other processing but do not actually attempt the unmount. (This is most useful in conjunction with -v,
to see what umount would attempt to do).
-R Take the special | node argument as a path to be passed directly to unmount(2), bypassing all attempts to be smart about mechanically
determining the correct path from the argument. This option is incompatible with any option that potentially unmounts more than one
filesystem, such as -a, but it can be used with -f and/or -v. This is the only way to unmount something that does not appear as a
directory (such as a nullfs mount of a plain file); there are probably other cases where it is necessary.
-h host
Only filesystems mounted from the specified host will be unmounted. This option is implies the -a option and, unless otherwise spec-
ified with the -t option, will only unmount NFS filesystems.
-t fstypelist
Is used to indicate the actions should only be taken on filesystems of the specified type. More than one type may be specified in a
comma separated list. The list of filesystem types can be prefixed with ``no'' to specify the filesystem types for which action
should not be taken. For example, the umount command:
umount -a -t nfs,mfs
unmounts all filesystems of the type NFS and MFS, whereas the umount command:
umount -a -t nonfs,mfs
unmounts all file systems except those of type NFS and MFS.
-v Verbose, additional information is printed out as each filesystem is unmounted.
