Reminds me of my first day of a computer programming class. My teacher told us to write down instructions on how to make a peanut butter and jelly sandwich. Then he would follow the instructions.
“Put the peanut butter inside two slices of bread.” He’d grab the jar of peanut butter and put the whole jar inside two slices of bread
“Grab a knife and scoop out the peanut butter.” He’d start stabbing the lid.
Beautiful analogy of what it’s like to deal with technology
For example I was creating systemd services and stuff because it is actually fun in comparison to init.d back in the days. Now I usually just copy paste tutorials and adjust it until my stuff works.
But my boot time somehow got longer O didn't noticed it at first, but when I finally digged to the problem it seems that for timed Services you don't want the Service to be installed(or even able to be instlled) and only enable the timer.
No tutorial told me that.
To be fair I didn't read the documentation on systemd. But who does?
