I yanked 
#Manjaro off of my mother's laptop and replaced it with a nicely customized 
#NixOS.
She now has a button to pull config updates from my #homelab and build it (also done regularly in the background). Old versions stay selectable at boot.
When she has a problem, there's shortcuts for #RustDesk and ad-hoc reverse #SSH tunnels.
I can test everything in a VM, then add changes, she'll pick it up eventually or right away.
Loosely inspired by @codemonkeymike's #nixbook.
