Backup and restore WSL2 vhdx, avoid 256GB vhdx limit for docker desktop WSL2 native

Review all steps to view the symptom this Gist addresses, customize a workaround to allow for >256GB Docker pulls safely on Windows, then perform a backup and recovery of the result (export and import). Please provide comments on any failures.

Determine the expected size of the docker-desktop-data volume

• Get the base image size + additional + all docker volumes using docker system df
• Add raw uncompressed size for alpine (50MB), docker for your version of windows (700MB) and linux (80MB)

Setting up multiple apache2 instances on Ubuntu 16.04

PHP handling on apache is done via modules of one sort or another, and running multiple version is problematic on a single instance. The solution is to run two instances of apache on the same machine. This allows one instance to run PHP 7 (the default on 16.04), and another can run PHP 5. Since normal http/https is on ports 80 and 443, the second instance will run on ports 81 and 444. Since it is running on the same machine, all file system and database access is the exact same.

All the commands herein have to be run as root, or with sudo prefixed to the command.

1. Read /usr/share/doc/apache2/README.multiple-instances

2. Run sh ./setup-instance php5 from /usr/share/doc/apache2/examples, where php5 is the suffix for the second site; all commands for the second site will have that suffix. This will keep all of the same configuration for all sites on the new instance, including SSL certif
