We have thousands of systemd services in Fedora. To "just add timeouts to things that take too long" would mean updating them individually. (Or maybe only some, but we don't really know which ones.) This is never going to happen, it's just too much work, and there is no clear clear understanding if it is "safe" for any specific service. Instead, the idea is to attack the problem from the other end: reduce the timeout for everyone. Once this happens, we should start getting feedback about what services where this doesn't work. Some services legitimately need a long timeout (databases, etc), and for those the maintainers would usually have a good idea and can extend the timeout easily. Some services are just buggy, and with the additional visibility and tracebacks, it should be much easier to diagnose why they are slow. Approaching the problem from this side is much more feasible. We'll probably have to touch a dozen files instead of thousands.
