        Some people can only reproduce systemd bug if the command is run in a loop. I've updated my blog post. https://www.agwa.name/blog/post/how_to_crash_systemd_in_one_tweet …

        Who care about responsible disclosure when we talk about SystemD? There were no resp disc. when systemd crashed my servers.

        That's exactly why you fix that upstream and in the distribution 1st. Then you post your rant on your blog @PCTuning_OW @__agwa

        I knew systemd was garbage, but this brings the definition of garbage to a whole new level.

        also why do systemd advocates often fall back to the "init scripts are hard to write" argument in defense to systemd?

        because there aren't many arguments in favor of systemd… and it’s wrong (since OpenRC provides easy init scripts)

        I think the argument is wrong bcs if a guy can't learn shell programming they should not administrate a unix box.

        that counter-argument won’t fly if the goal is to have regular people running GNU/Linux systems as home computers.

        regular ppl don't need to touch packages' integration bits. At all. They go with defaults, or choose another distro.

        by administration I mean that you have special need to customize the deployment and integration of packages.

        in practice you always have that need at some point or the other. It gives awesome flexibility — and *simple* scripts help.
