My box is currently running FC1 with a tailored 2.4.27 kernel. A home user desktop. I've never done an distro-upgrade between "fedoras" (or any Linux release...) The best way would be ... (I already have the four CD's waiting for): either a clean installation or maybe a leaded one by the Anaconda installer upon the FC1 partitions BUT "upgrading"? What does it implies exactly?: -First, to backup my whole /home partition to another place? Probably the answer here is "yes".. -It is possible to do that(FC1-->FC3) without stepping through FC2? It seems really very hard to add "the news" belonging to FC2 (renewed X-server, etc.) AND "the news" from FC3 too. I hope that the system doesn't end up messing up all. More, ALSA sound is currently working; I'm afraid that results of many efforts will last during a brief time... -Does it would happen anything if you don't have running an nptl kernel? I suppose it wouldn't. I mean..., would the upgrade be possible? -Also, I suppose I'd automatically loose some functionalities like webcam captures (due to pwc and pwcx modules in my case...---Thank you Alexander D. for that great links----) or ATI driver functionalities. -All those packages that once I installed from sources (tarballs) as they are not rpm's, are going to be lost? -Does it would make much sense to back up places like /usr/local, /usr/share where usually lives that sort of packages? I suspect that it wouldn't, because that binaries were built for an existing, concrete configuration; please, correct me if I am wrong, I am a shyly newbie. -Does it make any sense to backup the entire /etc directory since there would be there many files (as the XFree86 ones) that already doesn't exist in FC2? Would be a better idea to do a back up from some important files located there like fstab, modules.conf, etc. -Is it possible to change the repositories where yum and apt are pointing to? -without messing up things- That is, most of the packages and updates I get/did with FC1 were from a "group" of repositories that are compatibles between them, and I'd like to try now the another "group" -not an special, particular reason...- -Am I missing something important that needs to be born in mind? P.S. I've read the http://download.fedora.redhat.com/pub/fedora/linux/core/3/i386/os/RELEASE-NOTES-en.html Regards, Daniel Rodríguez
