It's possible there is a check on file or partition somewhere else, I could have missed it. Thanks for this code review. No, there is no such check. But this happens very late, when almost everything has already been stopped or killed, so swap space is almost unused. Time needed for swapoff is directly proportional to amount of swap space in use. Then we have a good "real life" use case. Swapoff seems to delay the shutdown (and maybe the restart) process. This would explain my observations. Sometimes shutdown is fast, sometimes slow and sometimes I

The next question is if this is a SystemD or Kernel problem. Greetings, Björn -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
