Sysadmin shock as Windows Server 2025 installs itself after labeling error

I believe Heimdal is supposed to provide patch management cross-platform, so similar to what RHN/WSUS/etc provide, but for all your platforms on one system.

Also, Microsoft has been aggressively removing the ability to control what patches you install, I assume because they don't test most combinatorics of possible patches running and people kept picking and choosing, so if you still wanted that level of control despite being told "don't do that", you would use a system like that.
