If you then mounted another
partition on /usr/local, everything below that mount point would be on the third partition,
while everything else below /usr would be on the second partition.

What happens if a remote file system is unmounted from your computer, and you go to
save a file in that mount point directory? You will write the file to that directory, and it
will be stored on your local hard disk. When the remote file system is remounted, however, the file
you saved will seem to disappear. To get the file back, you??™ll have to unmount the remote file system
(causing the file to reappear), move the file to another location, remount the file system, and copy
the file back there.
Mount points often mentioned as being candidates for separate partitions include /, /boot,
/home, /usr, and /var. The root file system (/) is the catchall for directories that aren??™t in other
mount points. The root file system??™s mount point (/) is the only one that is required. The /boot
directory holds the images needed to boot the operating system. The /home file system is where all
the user accounts are typically stored. Applications and documentation are stored in /usr. Below
the /var mount point is where log files, temporary files, server files (Web, FTP, and so on), and
lock files are stored (that is, items that need disk space for your computer??™s applications to keep
running).
