at first I thought library OS might have meant an OS meant for use at a library.
Honestly far less interesting to know I was wrong.
Me too. Honestly I was vibing on nostalgia for this: https://en.wikipedia.org/wiki/Dynix_(software)
yeah, same here, I was like "wow what an interesting side to their business, a whole operating system intended to serve public and academic libraries!"
Is it not? You link the "library os" and you no longer need an os (when running in a supervisor) IIUC.
