4.5 Disk Partitioning
The next phase of the installation setup involves deciding how the disk drive is to be partitioned and managed:
Figure 4-6
Assuming that this is a new disk on which an existing operating system is not present, the installer will provide the option to erase the entire disk and use it for Ubuntu (in which case the installer will calculate and implement a typical and recommended partition layout). If the security of the data stored on the disk is of paramount concern, select the option to encrypt the Ubuntu installation. If this option is selected a later screen will prompt you to choose a security key which will then need to be entered each time the system starts.
The option to use Logical Volume Management (LVM) is also strongly recommended to make the management of the disks and partitions on the system easier, a topic covered in detail in the chapter entitled “Adding a New Disk to an Ubuntu Volume Group and Logical Volume”.
