Selecting Debian partitioning scheme

The single partition (plus swap space) per disk scheme is the most common nowadays, as it is simple to create and manage. Multiple partitions may be used in the special cases mentioned previously, although, in general, the quality and speed of current backup utilities minimizes the need for separate partitions just for backup efficiency. Ifthe system has multiple disks and may require resizing or live migration in the event of hardware changes, then L VM should be considered.

In general, the Debian defaults follow best practice. This usually means a single root partition and a single swap partition. Ifthe administrator wants multiple partitions but isn't certain of the sizes required and doesn't want to use L VM, the defaults for the multipartition setup are a good starting point.

An exception to accepting the single root and single swap partitions default is the case of disk encryption discussed later. Ifimplemented via the Linux kernel, an unencrypted/boot partition is required.
