Ubuntu MATE 18.04 with encryption and hibernation side-by-side another OS.sh

### Ubuntu MATE 18.04 with encryption and hibernation side-by-side another OS
##############################################################################
###
### All filesystems/labels/layouts/sizes/etc... used are the defaults that would
### be used in an entire disk with encryption install.
###
### Exceptions are...
### 2 GiB for /boot to allow for plenty of older kernels
### 20 GiB for swap to account for 16 GiB RAM hibernating plus a bit extra
###
### This script assumes no Linux partitions, yet space has been made for them.
### An example layout before starting would be...
### /dev/nvme0n1p1	499 MiB NTFS System Partition
### /dev/nvme0n1p2	100 MiB EFI Partition
### /dev/nvme0n1p3	16 MiB MS Reserved Partition
### /dev/nvme0n1p4	95 GiB Windows NTFS Partition
