We can avoid this problem by not being so bump-happy. Adding an extra digit was painful when we did it before. A number of subtle things broke (like the output of file). Part of the problem here is that we want to ship FreeBSD 8.0 as '800100' which is just historical convention: * scheme is: <major><two digit minor>Rxx * 'R' is 0 if release branch or x.0-CURRENT before RELENG_*_0 * is created, otherwise 1. We could easily up that to '5' for the release so we have 499 entries. There aren't so many things that depend on this convention in the tree (I couldn't find any in a quick, informal survey). * scheme is: <major><two digit minor>Rxx * 'R' is less than 5 if release branch or x.0-CURRENT * before RELENG_*_0 is created, otherwise 5 or greater. I think is the only change we really need to make. : Better yet, we could automate the process somewhat and use : something like the major version of FreeBSD concatenated with the : SVN revision in lieu of __FreeBSD_version. I think this would be worse. First, external trackers would have difficulty updating this. Second, __FreeBSD_version is used to indicate kernel ABI points (at least recently, this is lame and should be reverted for the RELENG branch, but I digress). Third, ports use it to determine where we are and build things differently. I think this would complicate their lives and make documenting the points more difficult. This is one of those things that I don't think should be totally automated.
