Right. Sigterm should always be the first choice as a process may have the chance to handle that signal, free resources, save data etc. Sigkill pulls the rug out under it, which is a last resort, but may be necessary if the process can’t handle sigterm in reasonable time.

So the meme basically shows these two signals, both Windows and different Linux distributions have different ways to when they send each signal and how the user can use them.

So your PM is useless too? I feel like updates can be useful if others then go and help each other out with things.
