Description of problem: I have changed some parameters in eclipse.ini file, including: --launcher.GTK_version set to 2, because Gtk3 is very slow --launcher.XXMaxPermSize to 512M -Xms512m -Xmx4096m for performance Every single time eclipse is getting an update I have to manually edit the configuration because version numbers in "-startup" and "--launcher.library" change. These are configuration options a user usually won't change. On a semantic level I think those contents belong in two different files in different folders. The user-editable config belongs in /etc, e.g. in a file called /etc/eclipse.ini. The version-specific launcher.library and startup options belong somewhere below /usr, probably /usr/share/eclipse. Is that possible? Version-Release number of selected component (if applicable): eclipse-platform-4.5.1-5.fc23.x86_64 How reproducible: always
Short answer - no, it will require significant effort upstream for not that much benefit as GTK 2 option and MaxPermSize are probably to be gone really soonish.
FWIW, perm gen was removed in Java 8 so "MaxPermSize" is ignored, this setting should have no effect on Fedora 23.
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
