The maintenance time is a bit overestimated if you keep it simple.

On my homelab, I update everything every quarter and it takes about 1 hour, so 4 hours a year is pretty reasonable. Docker helps a lot with this.

And I’ve almost never run into trouble in years, so I have very few unexpected maintenance tasks.

EDIT: I am referring to a homelab that is only accessible for private purposes through a VPN.
