Suppose the mirrors we are talking about are up'n'running, some mirrors may be as much as 1 hour behind with the source tree. > 2) On the same note, is there any way to uniquely identify a global > revision of the FreeBSD source tree, comparable to revisions in > Subversion? From what I understand, there is no way to know if e.g. CVS > dates 2007.10.25.13.45.00 and 2007.10.25.13.46.00 represent the same > source code, except updating to both dates and seeing if any files change. This is my understanding too. Each file has a separate version number and there is no global revision number. If you still require such a feature, how about taking max(mtime()) as a global revision number?
