The most basic progress bar implementation (0% => no packages installed yet, 100% => all selected packages installed) is a rough approximation of how much of the installation is done. Now add further steps to the installation process, such as the "performing post-install configuration" which modifies the installed system. How much of the 100% does that account for? Perhaps 1% if it doesn't take much time. And what about packages' post-install scripts? If installation of a special package takes as much time as installing a hundred other packages, how to make that clear in the progress bar? One could try to come up with a formula for an approximation of an ETA value, but how accurate do you think that would get? Probably more important to the user is some sort of spinner, a sign of life, indicating that the installer is still working on something. > I've installed Linux since around the Red > Hat 5 days, and the install process was always rather clear.

Old Anaconda releases have displayed an ETA value instead, the "Remaining time", approximated of course (but it has not been an accurate approximation for many target machines, likely because the package post-install scripts already had a large influence on the actual installation time). -- Fedora release 17 (Beefy Miracle) - Linux 3.4.6-2.fc17.x86_64 loadavg: 0.15 0.26 0.22 -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
