I, too, like my systems to be booted up only a half way with half of the services being in an unknown/inconsistent state. > Combined > with the fact that the user sees nothing while systemd waits for something > (like 3 minutes) the user does not know (because he does not see anything on > the console) gives the impression that the system "hangs".

Then there are several things which should help you when things go south: 1) If the service fails and it's crucial to the boot process, you'll end up in the (apparently pretty despised by you) emergency shell, where you can go through all necessary logs to see what went wrong 2) By adding a simple "debug" to the kernel command line, or making use of systemd.log_level and systemd.log_target kernel cmdline options you can dump the entire boot process logic to the console. You can't do this by default, as it unnecessarily over-saturates the console line, which leads to a significant slow down of the entire boot process. Also, as everything is logged (as would any sane person expect), it would, again - unnecessarily, bloat the system journal You can't simply blame systemd that it refuses to boot when there's a service, marked as the system administrator as crucial, yet which is apparently broken in some way. > While the individual cause of such failures may not be systemd, the overall > effect of user frustration is very much due to systemd, giving it its bad > reputation. > So don't worry if people come to complain about many things here. The main issue is not about people complaining (that's actually something we want/need to), but in the version many of these users use. The systemd has come a long way for the past few years, and there's been thousands of changes to make things smooth and painless. But, of course, not all distributions use the bleeding-edge version of systemd, which then introduces certain problems: 1) An user complains about something which has been already fixed, yet not backported to their distro 2) Some distributions (like RHEL) base their systemd package on a certain version (like 219 in RHEL 7) and then backport only some patches from the upstream. Thus, upstream developers shouldn't/can't be expected to know what mixture of patches the user uses. In both cases, the downstream bug tracker is way to go. The downstream maintainers know their systemd package much better and can tell you, if it's an downstream-only issue, and a backport is necessary, or if it's indeed an upstream issue and they can guide you here (or they'd do that on your behalf). > Removing or changing the support URL might help to reduce the traffic here, > but it definitely wouldn't help against the bad reputation of systemd. Honestly, I'm kind of impressed you stamp the "bad bad systemd" phrase all over the place several times in your emails, yet you still expect people to be able to (willingly) help you. > To make systemd better, you really have to listen to the users' problems and > actually MAKE IT BETTER. I know this might surprise you, but that's how systemd got where it is now. We just need to filter out problems which have been already fixed, so we can focus on solving the outstanding ones (instead of going through hundreds of bug reports). >> >>> Just an idea... >>> >>> >>> Michael >>> >> >> -- >> PGP Key ID: 0xFB738CE27B634E4B > > > -- Frantisek Sumsal GPG key ID: 0xFB738CE27B634E4B
