====== File System Types ======
| ext2 | Dont use this, use ext3. Has the concepts of blocks, inodes and directories. |
| ext3 | Most popular, ok scalability. enhanced with journalling, supports POSIX ACL |
| reiserFS | small files, scales bigger than ext3, made by guy who killed his wife and child |
| XFS | extremely scalable, large files, Video, SGI irix |
| NTFS | Microsoft journaled FS, general MS purpose |
| isofs | Used by CDROM file system |
| Sysfs | It is a ram-based filesystem initially based on ramfs. It is use to exporting kernel objects so that end user can use it easily. |
| Procfs | It can be used to obtain information about the system and to change certain kernel parameters at runtime using sysctl command. |

====== Dir Structure and Partitioning Best Practices ======
Following is descriptions of common unix dir's and best practice partitioning of them

^ Dir   ^ Description                                                                               ^ Mount options, best practice                            ^
| /     | Root partition; incorporates the files under several dirs including /dev, /sbin, /tmp etc |                                                         |
| /home | Users home directory                                                                      | Set options local, nodev, nosuid, with quotas           |
| /usr  | Stores application programs; Linux/BSD binary programs are installed here                 | Set option nodev                                        |
| /var  | Stores log files, mails and other; files which keep changing size (log, or caching files) | Set option local, nodev, nosuid                         |
| /tmp  | Stores temporary files                                                                    | Set option nodev, nosuid, noexec option must be enabled |

Following is the code in **/etc/fstab**

<code>
/dev/sda1  /home          ext3    defaults,nosuid,nodev 1 2
</code>

Following is the code from an example **mount** command. Just running mount, gives you currently mounted fs's.
<code>
/dev/wd0a on / type ffs (local)
/dev/wd1a on /home type ffs (local, nodev, nosuid, with quotas)
/dev/wd0d on /root type ffs (local)
/dev/wd0e on /usr type ffs (local, nodev)
/dev/wd0f on /tmp type ffs (local, nodev)
/dev/wd0h on /var type ffs (local, nodev, nosuid)
/dev/wd0g on /var/log type ffs (local, nodev)
</code>

For more info please read man pages of fstab, mount, fdisk or http://www.cyberciti.biz/tips/the-importance-of-linux-partitions.html

==== fstab options key ====
  * **nosuid** - Do not set SUID/SGID access on this partition
  * **nodev** - Do not character or special devices on this partition
  * **noexec** - Do not set execution of any binaries on this partition
  * **ro** - Mount file system as readonly
  * **quota** - Enable disk quota

Above options can be set only if you have separate partitions.
