[Bug 555288] New: optimizing installation startup speed
http://bugzilla.novell.com/show_bug.cgi?id=555288 Summary: optimizing installation startup speed Classification: openSUSE Product: openSUSE 11.3 Version: Factory Platform: Other OS/Version: Other Status: NEW Severity: Enhancement Priority: P5 - None Component: Installation AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: cyberorg@opensuse.org QAContact: jsrain@novell.com Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.4) Gecko/20091016 SUSE/3.5.4-1.1.2 Firefox/3.5.4 Just before the installation starts: /usr/share/YaST2/clients/inst_prepareprogress.ycp runs: if (Mode::live_installation()) { string cmd = sformat ("du -x -B 1024 -s %1", "/"); y2milestone ("Executing %1", cmd); map out = (map)SCR::Execute (.target.bash_output, cmd); y2milestone ("Output: %1", out); string total_str = out["stdout"]:""; live_size = tointeger (total_str); if (live_size == 0) live_size = 1024*1024; // 1 GB is a good approximation } "du -x -B 1024 -s %1", "/" takes really long time, approximately 8 minutes on openSUSE Edu live DVD where the compressed size is 2.8G and normal size is about 8G. df should be used in place of du as it is much faster returning the size of / if that is all it requires.

On the other hand, it should still be sufficient for the progress report. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

That way du will only be required to run once during building the image, not on everyone's PC when installing. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

But bars that can hit 100% while the progress isn't done are nonsense.

Which will mean that the progress will never hit 100%. As package installation (resp. copying the image) is not the last item in the proress, it should not do any harm - there may just be one bigger step around, say, 90%. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
