I have an old ThinkPad 11e running Debian that I have repurposed into a home server. It’s only supposed to run TVheadend. I don’t need any other services for now, but later on i might add a few using docker.
Is it enough to set multiuser.target as default to disable gui and keep the system always on?
How can I disable all unnecessary services and minimize power usage?
No, hard disagree.
I have many thousands of dollars worth of hardware. I have seen the results of a surge. I have seen a NAS reduced to a paper weight. You’re making incredibly silly assumptions here - this has nothing to do with uptime, and everything to do with protecting your equipment.
You will not ever convince me otherwise, because I’m not willing to dump thousands of dollars on replacements because someone on the internet thinks it has anything to do with uptime.
You are wrong.
Edit: anywhere that weather exists is an area with “unreliable electricity”. Full stop.
