For the arch machine, not a chance. For the fedora silver blue machine? Yeah the process was super easy. The hardest part was probably getting the iso on a USB stick, but my wife walked through the initial setup with me via the GUI installer. It was no harder and much faster than a Windows install via a USB stick.

I don't think my mom could do it solo.

Regardless, it's pretty much set it and forget it, so if I'm visiting - could setup in 20 minutes and from that point onward no intervention required from me.

It's not rocket science but I get that some people will just want to use whatever is pre installed or whatever was configured for them.
