Feature changed by: Andreas Jaeger (a_jaeger) Feature #312756, revision 6 - Title: Installing Opensuse Distro with YAST from source + Title: Installing openSUSE Distro with YAST from source - openSUSE Distribution: Unconfirmed + openSUSE Distribution: Rejected by Andreas Jaeger (a_jaeger) + reject reason: Testing and bug reporting are challenges, let's tune the + most critical parts instead. Priority Requester: Important Requested by: Elmar Haag (hans_linux) Partner organization: openSUSE.org Description: I would like to see a installation option in YAST that would allow me to install update a installed system from source. Maybe using the following steps: 1.) Do a normal install from the distribution DVD or a Network install and configure the system as required. 2.) Optionally download the sources for each library and application, compile with user specified complier flags, such as CFLAGS="-mtune=native - march=native -O3", MAKEOPTS="-j5" etc. 3.) Replace the original vanilla libraries from the distribution DVD and their updates with the complied applications. Business case (Partner benefit): openSUSE.org: The advantage would be a system optimised for the specific hardware on which it is installed resulting in best possible performance for application that are compiled with the same compiler optimisation flags. Discussion: #1: Dean Hilkewich (deanjo13) (2011-08-20 18:26:35) Why not use OBS for that? #2: Elmar Haag (hans_linux) (2011-08-24 08:55:23) (reply to #1) I would do it if I would know how to do this using OBS. + #3: Andreas Jaeger (a_jaeger) (2011-08-28 10:22:17) + For those routines, apps and libraries that would benefit performance, + we could add them to the distribution so that it helps all. We do this + already with a e.g. an i686 glibc and glibc that contains library + routines selected based on the cpu. Some other critical libs do the + same. Let's not build for everybody their own distribution - there's + Gentoo for that - since it will make bugreporting and testing harder + (you have to verify that a bug exists not because of the self-built). + Btw. OBS does not have the bandwidth and space so that each openSUSE + user can build a whole distribution. + I suggest that you do a profiling of your system and figure out where + the performance bottlenecks are and then figure out how to solve those + for everybody in a good way. -- openSUSE Feature: https://features.opensuse.org/312756
