I want to reinstall Ubuntu from scratch.
I have read (here and here) that it is recommended to have 3 partitions for the desktop installation: root, home and swap as having a separate home and root can simplify the process if you want to upgrade or reinstall Ubuntu (if you break something by mistake).
But there is no type of formula (that I can find) on how big each partition should be. I know this is somewhat dependant on what you plan to install. I want to have flexibility down the line to install new software without having to worry about shifting the partition sizes around.
Does anyone know of a formula or percentage breakdown that they have used to successfully calculate partition sizes?
i.e. x% of space will be allocated to the swap, y% of space to the root partition and z% of space to the home partition
