I have to admit that I have no idea how they are organized, there could be very good reasons for doing it the current way. However, I was actually only suggesting that the packages be sorted by "popularity", where "popularity" is the number of packages which depend on the package in question (this would need to include both direct and indirect dependencies). The most-depended-upon packages would go on the first disc and the least-depended-upon packages would go on the last. If you move from first to last, then all dependencies are automatically satisfied. While this should put most of the common packages on the first disc, you could have a frequently installed package that was not highly depended upon that was placed on the last disc. If your aim was to minimize the number of discs that had to be downloaded this ordering would be less that ideal. However, there are a large number of orderings which still satisfy the dependencies; the one I gave is just a good starting point. If you wanted, such packages could be "promoted" in the ordering by placing them immediately after all of their dependencies had been satisfied. In fact, you could do this recursively for every package that the particular package depended upon so that it occurred as early in the ordering as possible. And if you had a list of such "important" packages this could clearly be performed for each (if you started with the least important and moved to the most, you could ensure that the most important were placed earlier in the ordering).

I agree that fiddling with pkg_add to place the packages neatly on the disc would probably not be worth the effort, but I'm not sure that it is necessary. In order for the method I suggested to work, sysinstall would have to be modified to attempt installation in the selected ordering. If you had a list of the packages in this ordering, you would only have to flip the "please install this one" bit for the selected packages, and then traverse the list in order installing/ignoring each package. Since all dependencies would be satisfied by virtue of the ordering, pkg_add would find that every dependency had already been satisfied and should not cause any problems. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
