Hello, As a substitute or a complement to something similar with fedora legacy, it has more or less been suggested to allow for an upgrade path to RHEL. Should we set this as an objective for fedora? It could be something like ensuring that yum update can take you to the next fedora release and then to the corresponding RHEL, without rebooting (except for kernel upgrades, of course), or changing radically configuration file. So, for example, FC6 users could upgrade to RHEL5, and FC4 users could upgrade to FC5, then FC6, then RHEL5. In such setting I don't think that we should ensure such upgrade path for all the apps, only 'critical' apps, likely to be usefull on servers, like network daemons, for example. Also we could only do that for packages that are in RHEL+EPEL. This is currently not supported, and not an explicit goal, although there are instructions for the upgrade between FC versions: http://fedoraproject.org/wiki/YumUpgradeFaq >From reading this document, it appears that this kind of upgrade isn't possible due to kernel incompatibilities between FC4 and FC5. In case we want to ensure the upgradeability I was referring to, such situation should be avoided. Maybe this goal is too conflicting with other fedora goal, especially being bleeding edge. The big constraint is that incompatible changes which requires rebooting or changing configurations must all happen between the fedora release preceding the RHEL release and the next fedora release (in our case, all the incompatible changes should be done between FC6 and FC7). In any case I don't think we should support in any sense this kind of things, but maybe we could have this as a goal, such that maintainers have this issue in mind when they make their decisions. We could also do some tests like EVR tests similar with what is currently done for Fedora, but between the fedora version used as a base for RHEL and RHEL (in our case between FC3 and RHEL4 and FC6 and RHEL5) to ensure upgradability. And lastly we would then have to coordinate between the maintainers working on the different distros, ie between fedora and RHEL/EPEL maintainers (I guess they are more or less the same people, but maybe there may be special cases). Another thing is that I don't think this should be a short term goal. In my opinion there is already enough to be done with the merge, EPEL beginning and I guess people working on RHEL5 are busy, but maybe it could be doable to begin to experiment with such idea (if it is not immediatly rejected ;-) between RHEL5 and RHEL6 and try to make it happen for RHEL7? -- Pat -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
