Books for you

The last two fields (in the example, all are marked 0 0 except for /, which is 1 1) are digits
that other programs use. The fifth field tells dump, a venerable Unix backup program,
whether to back up the file system when it is run: 1=Yes, 0=No.
The last field tells the file system repair tool fsck how to interact with each file system:
0=Never, 1=Run at a designated time, and 2=Run periodically, but less often than the 1s.
You should not have to edit /etc/fstab more than once, but if you have problems with
the OS not seeing a file system (CD won??™t run, can??™t copy files from a floppy or Zip disk,
for example), this is usually the place to start troubleshooting.
Logical Volume Management (LVM)
The dilemma in partitioning has always been how large to make each partition (also
known as a volume). Too often, you just accept a default, or make a wild guess about how
much space you??™ll need for the data you plan to put on your partition. One day, you??™ll
find yourself painfully short of space on one volume, while having a ton of room on
another.
