Customized Linux paritioning during OS installation

WORK IN PROGRESS – PLEASE DO NOT USE

Customizing your Ubuntu installation to manage disk space usage.

Some users like / need to manage their system’s disk space allocation.

Some reasons are:

1. Multiple OS installations (dual boot)
2. Protecting user data (/home directory contents) while re-installing the OS.
3. Customizing the Plex installation and moving that data to a safe place like /home

This quick How-To shows a simple example of custom partitioning in a VM and allocating space for the OS and user data separately.

In this example, a 250 GB virtual HD (vda) is utilized. It is partitioned as:

1. Boot partition without UEFI ( size as 536 if UEFI / ESP )
2. 128 GB for the root file system
3. 128 DB for the home partition.
