Hi, I can't answer all your questions, but will take a shot at a couple. You should check out the handbook at:
http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/ports.html and http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/porters-handbook/ For more complete information.

Am I understanding > this correctly? No, not quite. They are two separate things, but can be run from the same supfile in the same csup run. By the way, cvsup has been replaced by csup which is now in the base system from about 6.2 on. or maybe it was 6.1. Here is the relevant part of my supfile: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- # *default host=cvsup.FreeBSD.org *default base=/var/db *default prefix=/usr *default tag=RELENG_6_2 *default release=cvs *default delete use-rel-suffix *default compress ## Main Source Tree. # The easiest way to get the main source tree is to use the "src-all" # mega-collection. It includes all of the individual "src-*" collections. src-all ports-all tag=. doc-all tag=. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- This gets 6.2 OS and the latest ports and docs. You could put tag=RELENG_6 and get the latest OS updates for 6.xx (but not the latest over all) included. > Assuming I am, my main confusion concerns just how these two systems > actually interact and relate to each other, and whether there are any > requirements connecting updating each of them together?

They do interact and there can be problems. The OS has versions. The ports tree does not. It is just the latest that has been supplied by the port maintainer. As the OS gets older, it becomes more likely that a giver port is too new for it and may not build or run on it. It can happen the other way around too - the OS is too new for the present condition of the port. But, there is an attempt to keep this from happening. When the head of an OS branch is getting to the point of making a new RELEASE, then a freeze is put on code in the OS thus making a temporary non-moving target to build all the system plus the ports against. It is generally up to the port maintainers to make sure their port[s] can build to that frozen image. When all seems to build, run and test together then a RELEASE is made. Then the branch is unfrozen and changes start coming in again - both to the base OS and to the ports. In general, the OS versions are managed so that anything that will run in one version of a main branch will run in another. eg, if it will run in 6.1, it should run in 6.2 and 6.3. But it may well not work in 7.xx because os some non-compatible change introduced in the new major branch level. That is the main part of the decision to create a new main branch and what usually determines whether some change will be introduced in a lower branch or reserved for a higher branch. But, again, the ports are not limited to a version so in some cases, especially when signiicant time has elapsed, a port may not build or run on some version. You may need to go back and get a legacy version of the port to make it run, or note the changes and tinker. In practice, though, it usually works well to keep your OS and ports up to date. Developers and maintainers try to make things work and to keep them compatible as far as possible. ////jerry > > One of the things which caused me to wonder about this was that some > time back I tried FreeBSD out for a while and ran into some oddities > concerning the ports system.
