[NFBCS] Keeping Linux Tidy

Sat Apr 3 19:24:03 UTC 2021

I like FreeBSD jails for this, although Linux doesn't use jails in the 
same way.

Alternatively, create a vm for testing apps/etc, then create a snapshot 
every time you update. Use that snapshot to test, and if you like it 
install on your host, otherwise just reboot and restore to your last 
good snapshot.
