Filesystems

In UNIX, there is only one root file system that spans many disks.

Different directories may exist on a different physical disk (storage device).

Automatically Mounted File Systems

The file /etc/fstab lists filesystems mounted when the system booted.

The actual mount can be listed with mount:

 
/dev/hda1           /                   ext2    defaults        1 1
/dev/hda6           /tmp                ext2    defaults        1 2
/dev/hda7           /var                ext2    defaults        1 2
/dev/hda8           /usr                ext2    defaults        1 2
/dev/hda9           /home               ext2    defaults        1 2
/dev/hda5           swap                swap    defaults        0 0
