FYI this is the hello world example. Took me some time to read all that log.

dadada commented 8 months ago

systemd-run-example-hello_part works for me on the main branch. Could you provide more detailed instructions on how to reproduce the issue?

wucke13 commented 8 months ago

This was a copy of the hello_part example with all start process calls removed

wucke13 commented 8 months ago

Would we rather like a warn or a debug type log for when a partition window starts which has 0 processes scheduled?
