Don’t worry, I would never think to do this to a server, let alone one of 
yours, Jacob’s, someone else’s, or another libre-soc server. Unfortunately,
I already have done this to my local pc, but I don’t plan on doing this again. 
I had spent the past week doing the manual investigation and recovery 
method and was still encountering transient bugs and problems. If this 
were a server I would have—preferably not have been so careless 
in the first place, but barring this—continued on in my debugging, and 
reached out to the list for help if I was still unable to solve the issues 
after a second concerted effort. This is the procedure I will follow should
I unfortunately find myself with a buggy OS in the future, however I am 
planning to be much more careful and mindful about my installations 
and configurations moving forward.
