If you choose automatic partitioning, the installation program deletes all data in all existing partitions
of any kind and decides how to partition the disk for the new version.
If you choose automatic partitioning, a server-class installation removes ALL existing partitions on
ALL installed hard drives, so choose this installation class only if you are sure you have nothing you
want saved! When the installation is complete, you will find the following partitions:
• A 256 MB swap partition.
• A 256 MB partition (mounted as /).
• A partition of at least 512 MB (mounted as /usr).
• A partition of at least 512 MB (mounted as /home).
• A 256 MB partition (mounted as /var).
• An 8 MB PReP Boot partition in which the Linux kernel or the boot loader resides.
This disk partitioning scheme results in a reasonably flexible filesystem configuration for most server-
class tasks.
2.5.3 Custom-Class Installations
The custom-class installation allows you the most flexibility during your installation. The worksta-
tion-class and server-class installations automatically go through the installation process for you and
omit certain steps. During a custom-class installation, you must decide how disk space should be par-
titioned. You have complete control over the packages that will be installed on your system.
The minimum recommended disk space requirements for a custom-class installation are as follows:
• Custom (minimum): 300 MB
• Custom (choosing everything): 2.4 GB
At this point, you should have already planned your disk space requirements so that you know how
much additional space is needed beyond what the Red Hat installation program requires. You should
have also determined where that space will come from, whether from a virtual disk, a physical disk,
or a combination of the two. Once you have completed the installation, altering the sizes of your
partitions can be disruptive.
What a Custom-Class Installation Will Do
As you might guess from the name, a custom-class installation puts the emphasis on flexibility. During
a custom-class installation, you can choose how disk space should be partitioned. You have complete
control over which packages will be installed on your system.
The following list may help those of you who are trying to decide which installation class will better
suit your needs. If you think you will have trouble performing any of the tasks on this list, you should
