How to Open Multiple Instances of Libreoffice on Linux

[@johnwhitneypettit6945]

Brilliant, easy-to-understand. Now to streamline it, a script to mount the contents of ~/path-to-config/libreoffice/ as multiple unionfs-fuse or aufs with fuse mounts. Script options might include: upon clean exit -- or with each change to the fs even -- backup one instance's config directory to another instances', but not vice versa. E.g., changes to macro code or shortcut assignments automatically apply to parallel instances e.g. from instance0-doc0 --> instance1-doc1, but toolbar definitions or configurations modified under instance1 do not affect instance0.
