I now always stay around in the movie theater to see who the sysadmins were that worked on the film, for solidarity reasons. :-) Pretty much all the movies these days have them, which I would have never imagined would be the case back in the '80s when I started this career path.
Huh I’ve never noticed a sysad credit in a credits roll. Are they labeled as something else?
It depends, sometimes yes sometimes no. Toy Story 2 says "systems administrators & support" for example: https://youtu.be/4rL_4Xqak1Y?si=R2ykfdSarIjjGDZP&t=288
