“…please consider carefully how you want to size your
partitions. I did this on a 15 GB virtual image, hence swap, root,
home are quite small. As I’ve just told, I will make a seperate
home partition. If you need to reinstall, you can just follow this
guide again BUT leave the /home partition untouched during
installation. Once you’ve setup then boot, swap and root, you can
manually add the /home partition into the local filesystem and
setup it up to automatically unlock by a key.”
