Fedora LiveOS, journal missing ~25s of early boot
by Chris Murphy 31 Jul '19

31 Jul '19

Hi, Summary: On Fedora LiveOS, e.g. Fedora-Workstation-Live-x86_64-Rawhide-20190728.n.1.iso, the journal is missing the first 20-30s of all boot/startup related messages. The reason is a bit complicated, systemd-journald appears to have a bug wanting keep_free space too high, and Fedora's lives have had shrinking free space consistently over time as the "payload" gets bigger. The result is now systemd-journald almost immediately vacuums the first journal file, deleting it, causing the loss of early boot and startup messages. Why I think Anaconda team might care: LiveOS is inherently a non-deterministic environment for the installer, and losing a bunch of early boot and startup messages like all the liveos assembly, the overlay (whether dm or overlayfs based in the future), networking, udev and other non-kernel device discovery, and dracut debug messages - don't exist in the journal and quite a lot of such messages for whatever reason do not forward to console or kmsg when using systemd.journald.forward_to_X parameters. Therefore if the journal is deleted, the messages are flat out gone and any troubleshooting and introspection is really difficult. I proposed this as a blocker bug. https://bugzilla.redhat.com/show_bug.cgi?id=1715699 It's been rejected twice, mainly because the Fedora Basic Release Criterion for system logging applies to the post-installed system. It doesn't apply to any of the installer images. So there is a proposal over on test@ list to change the location of this requirement so that it applies to installer images. And I figured installer devs might have an opinion if this is blocker worthy. https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org/… https://fedoraproject.org/wiki/Basic_Release_Criteria#System_logging -- Chris Murphy

Anaconda modularization and your addon

Good day Thomas, I'm working on Anaconda (Fedora/RHEL/CentOS installer) and we have recently seen your presentation about addon on Anaconda you are using for the CERN purposes[0]. That's great to hear you are using and extending our project. Hope you like how Anaconda progress. I want to ask you about current status of this addon. If you are using it or testing it on Fedora or if you are planning to adapt it on RHEL- 8? The reason is that we are doing a bigger improvement of how Anaconda is working on the backend side and it will probably touch your addon. We want to provide you a stable API which you and even us will use. You can look on my presentation [1] and our blog [2] unfortunately it's little bit outdated but the main idea stays the same. You can also look on the recent upstream changes, all the work we are doing is more or less used on Fedora even now. I writing you mainly because we want to avoid breaking of your addon. In case you will have problems with the addon thanks to the transition to a new solution please feel free to contact us on mailing list: anaconda-devel-list(a)redhat.com or IRC: freenode #anaconda [0]: https://www.youtube.com/watch?v=Fbml_WGMnoQ&feature=youtu.be&list=PLuRtbOXp… [1]: https://www.youtube.com/watch?v=00W8SsRrU8g&t=1s [2]: https://rhinstaller.wordpress.com/2017/10/09/anaconda-modularisation/ https://rhinstaller.wordpress.com/2017/11/23/anaconda-modularization-instal… Best regards, Jirka
