The Fedora ppc64 guys have a patch they are working on, they should be attaching it to this BZ when it's ready. Created attachment 521203 [details]
move images/install.img to LiveOS/squashfs.img
The patch actually is for the treebuilder branch of lorax, reassigning to Will Woods. I applied a version of the patch in comment #13, but we'll still need a pungi patch to make the pungi-built images work. See bug 748939 for that patch. We're currently using a custom pungi to create our images, so it isn't a beta blocker but a 'nice to have' it fixed I would like to know that, starting with a clean system, I can install the treebuilder branch and have it build the exact same DVDs as you do. Right now, I don't know if my build system is out of sync... :( This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 WONTFIX if it remains open with a Fedora 'version' of '16'. 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 prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 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 to click on "Clone This Bug" and open it against that version of Fedora. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
