I don't think it's a jump. I'm glad you're responsive to these concerns. However, I don't want a Fedora release to ship with many more such concerns unresolved. The place to address these things is in a development tree. > And anyway, *2* "incidents" don't really make up a pattern, do they? I actually count four that I've noticed so far: - chkconfig and service not working as expected - shutdown delay option destructively ignored - filesystems marked 'noauto' getting mounted automatically - runlevel 3 reporting itself as runlevel 4 Now, you have been good about providing a solution for these. But those are just the things *I've* noticed, and let me assure you that I am quite far from the _most_ crotchety set-in-his-or-her ways old-school sysadmin. The pattern I see is that each time, you respond initially with (paraphrased) "It's not broken -- we've made it better!" before implementing the fix. So, I'm honestly asking: what are the odds that these few things are the only improvements that cause a disruptive change to user interaction? I don't think it's unreasonable to wonder if there are other changes which fit this category. > If you'd put the bar for some other package as high as you are putting > it for systemd, then well, maybe the Linux kernel isn't ready for F14 > yet either? ;-) If we were running some other kernel, and the Linux kernel came along and made a whole bunch of changes to user interaction, yes, I would indeed say that it's not ready yet. > A little bit more optimism, please!

In a lot of cases, that's probably okay -- but we need to make sure that all of these things make the release notes. And as we've seen, in many cases what other people think matters turns out to surprise you.

This is such a substantial change, and the system so young, that I'm really afraid that one such cycle isn't going to be enough. I don't think it would be a failure to say that we should leave the system as optional for F14 and aim to make it default for F15. > That all said if you have a look on the number and quality of open bugs > of systemd for F14 then it appears to be a lot stabler and more polished > than probably most of the stuff in the current base system.

I'm concerned there aren't enough eyeballs yet -- and people don't necessarily no where to look, because the changes can be in unexpected areas. It took me a few minutes to figure out that systemd was mounting my noauto filesystem, for example. -- Matthew Miller <mattdm@xxxxxxxxxx> Senior Systems Architect -- Instructional & Research Computing Services Harvard School of Engineering & Applied Sciences -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
