[Tip] The Linux MOUNT command

[fossette]

For those who understand better visually, here is an example of the Linux mount command:

Before the mount, partition B is invisible

After the mount of partition B onto the home directory

IMPORTANT: Note that the original content in the home directory before the mount command disappears until the partition B is unmounted by the umount command.
