And also I'm seeing a change in the behavior I previously described, the percentage progression to 100% does a pretty decent job of ending up at 100% when it's really done. -- Chris Murphy ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org

A famous progress bar was the one visible during the Mac os X boot process, that was based on the last boot time and not on any estimation. What I mean is that, while percentage​goes on, progress bar is full from start to finish, there are no progresses from 0 to 100% And I haven't spotted such issue on previous versions of Fedora.

A bunch of research has been done on progress estimation, and it's actually a hard problem. But a way to make it more reliable would be having installation milestones, e.g. maybe 10% is always the completion of partitioning, fsck, and mkfs; and 90% is always the making of the initramfs. We have a textual description of what's going on with the installation, and tying those things to some percentage sounds more reliable and consistent. If I do a default installation (ext4 on LVM on a HDD using CFQ scheduler) the progress is fairly sane up until initramfs generation where it hangs at 100% for a while. If I do a Btrfs installation on SSD using noop scheduler, it goes pretty much from 0% done to 100% done right after mkfs, and just stays there through rsync copy, and initramfs creation, and bootloader config. Anyway, maybe the problem is the progress bar is trying to do too much intelligent estimation but ends up making assumptions that can be wrong. So instead maybe make it less smart, less dynamic. -- Chris Murphy ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org
Progress bar
During installation, the progress bar is "full", all blue I mean, during the installing software process. Even if the percentage of the installation is not 100% I'm using Fedora-Workstation-Live-x86_64-26-20170420.n.0.iso Is this expected?

Cheers, Gavi n Right, anaconda doesn't have a progress bar, but a stage indicator. Unfortunately it is displayed as... a progress bar. I tried to explain the differences and propose some improvements to Martin Sivak, a former Anaconda developer, but he wouldn't listen. He doesn't work on Anaconda anymore, so maybe someone else might be more open to this dialogue. I suggest that you write into anaconda-devel mailing list [1], or/and create a bugzilla report with your suggestions.
