Caution:

56.

You may run out of hard drive space in your home partition due to the sub-division of the drive into fixed-size partitions. This may occur even if the other partitions have plenty of usable space. Good and logical partitioning requires you to predict how much space each partition needs.

57.

For new users, home users and other single-user set-ups, a single root (/) partition with a swap partition would be the easiest and the most convenient to create and use. However, for multi-user systems or computers with lots of disk space, it is best to have the /home, /tmp, /usr and /var directories as individual partitions separate from the root (/) partition.

58.

root: Also called the slash directory, it is the highest directory of the directory tree. When creating the root partition, you need to ensure that the root should contain the /etc, /bin, /sbin, /lib and /dev directories, otherwise you will not be able to boot-up the system. You also need to ensure that the root partition is allocated at least 150-250 MB of disk space.

59.

/home: This directory contains all user-specific files and data. On a multi-user system, every user will store personal data in a sub-directory of this directory. The size of this directory would depend on the number of users using the system and the files they store in this directory. Ideally, you should plan the disk space for this partition based on your planned usage. In general, about 100-MB disk space can be allocated for each user. However, you may need to reserve a lot more space if you are planning to save a lot of multi-media files in your home directory.

60.

It is good practice to have /home on a separate partition because it allows for a smoother transition from one distribution to another.

61.

/var: This directory contains variable data, such as news chapters, e-mails, Web sites, databases and the packaging system cache. The size of this directory also depends on system usage. Most probably, the size of this directory would be dictated by your usage of the Ubuntu package management utilities. If you plan to install all the packages that Ubuntu offers, you need to allocate 2 to 3 GB of space for the /var directory. However, if you want to save hard disk space and do not plan any major software updates, you can get by with as little as 30- or 40-MB disk space for the /var directory.

62.

/tmp: This directory contains temporary data created by programmes. Some applications, including archive manipulators, CD/DVD authoring tools and multi-media software also use this directory to temporarily store image files. You need to plan space allocation for this directory based on your usage of these applications. for this directory.

63.

/usr: This directory contains all user programmes (binaries), their documentation and supporting libraries. This directory tends to use the maximum space on the hard disk. Therefore, you should provide at least 500-MB disk space for this directory. But, you need to increase this space depending on the number and types of software packages you plan to install. Based on your planned usage and the available disk space, you may allocate 1.5 to 6 GB of disk space for this directory.

64.

The /usr partition is sometimes referred to as User System Resources and not user as was originally intended.
