Partitioning notes

Partitioning for a modern Linux distribution is generally very simple, however the introduction of GPT and UEFI booting does bring new complexity to the process. When creating your new partition table you will need a partition for the root filesystem, along with a swap partition and possibly another partition or two to facilitate booting, if required.

Note that if the disk has already been initialised, the top of the cfdisk screen will show the partition layout already present: Label: dos for the MBR scheme, Label: gpt for the GPT scheme. If you just want to erase the partition table before starting the installer, use wipefs(8). Otherwise, you can run cfdisk(8) manually with the -z option to start with an uninitialised disk layout; cfdisk will prompt you for the label type before continuing to the main screen.

The following sections will detail the options for partition configuration.

BIOS system notes

It is recommended that you create an MBR partition table if you are using a BIOS boot system. This will limit the number of partitions you create to four. It is possible to install a GPT partition table on a BIOS system, but grub will need a special partition to boot properly.

UEFI system notes

UEFI users are recommended to create a GPT partition table. UEFI booting with grub also requires a special partition of the type EFI System with a vfat filesystem mounted at /boot/efi. A reasonable size for this partition could be between 200MB and 1GB. With this partition setup during the live image installation, the installer should successfully set up the bootloader automatically.

Swap partitions

A swap partition is not strictly required, but recommended for systems with low RAM. If you want to use hibernation, you will need a swap partition. The following table has recommendations for swap partition size.

Boot partition (optional)

On most modern systems, a separate /boot partition is no longer necessary to boot properly. If you choose to use one, remember that Void does not remove old kernels after updates by default and each image will take at least 20MB, so plan accordingly.

Other partitions

It is fine to install your system with only a large root partition, but you may create other partitions if you want. One helpful addition could be a separate partition for your /home directory. This way if you need to reinstall Void (or another distribution) you can save the data and configuration files in your home directory for your new system.
