I will soon have a few different ARM machines that I can do testing on. Please let us know[1] your test suite if you want me to try to substantiate your pessimism. Here is the best reason I've heard for prelink on today's standard, memory-constrained ARM device: http://lists.laptop.org/pipermail/devel/2011-May/032011.html Please keep at least the option to enable prelinking in Fedora, especially before anyone has any performance numbers. > Gordan Martin 1. A wiki page about prelink on ARM would probably be even better than a mailing list post. I will start one if nobody beats me to it.
