In Fedora 15, all of the "stage2" content, that is anaconda and supporting libraries, were made part of the initrd. This was a change from previous releases, where the initrd was just stage1, that was enough infrastructure to find and launch stage2. Moving it into the initrd resolved a lot of outstanding issues with Anaconda, and removed a lot of duplicate code that was difficult to maintain. There was a jump in memory requirements, as now all of that content was loaded into memory, and there are potential fixes being worked on. However they were deemed too risky for Fedora 15 and thus did not make it. This is why the install kernel requires significantly more ram than the kernel you'd use after you've done an install. - jlk -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
