Staying current with FreeBSD

Contributed by &a.jkh;. What is FreeBSD-current?

FreeBSD-current is, quite literally, nothing more than a daily snapshot of the working sources for FreeBSD. These include work in progress, experimental changes and transitional mechanisms that may or may not be present in the next official release of the software. While many of us compile almost daily from FreeBSD-current sources, there are periods of time when the sources are literally un-compilable. These problems are generally resolved as expeditiously as possible, but whether or not FreeBSD-current sources bring disaster or greatly desired functionality can literally be a matter of which part of any given 24 hour period you grabbed them in! Under certain circumstances we will sometimes make binaries for parts of FreeBSD-current available, but only because we're interested in getting something tested, not because we're in the business of providing binary releases of current. If we don't offer, please don't ask! It takes far too much time to do this as a general task. Who needs FreeBSD-current?

FreeBSD-current is made generally available for 3 primary interest groups: Members of the FreeBSD group who are actively working on some part of the source tree and for whom keeping `current' is an absolute requirement. Members of the FreeBSD group who are active testers, willing to spend time working through problems in order to ensure that FreeBSD-current remains as sane as possible. These are also people who wish to make topical suggestions on changes and the general direction of FreeBSD. Peripheral members of the FreeBSD (or some other) group who merely wish to keep an eye on things and use the current sources for reference purposes (e.g. for reading, not running). These people also make the occasional comment or contribute code. What is FreeBSD-current NOT?

A fast-track to getting pre-release bits because you heard there's some cool new feature in there and you want to be the first on your block to have it. A quick way of getting bug fixes. In any way ``officially supported'' by us. We do our best to help people genuinely in one of the 3 ``legitimate'' FreeBSD-current categories, but we simply do not have the time to help every person who jumps into FreeBSD-current with more enthusiasm than knowledge of how to deal with experimental system software. This is not because we're mean and nasty people who don't like helping people out (we wouldn't even be doing FreeBSD if we were), it's literally because we can't answer 400 messages a day and actually work on FreeBSD! I'm sure that, if given the choice between having us answer lots of questions or continuing to improve FreeBSD, most of you would vote for us improving it. Using FreeBSD-current

Join the freebsd-current and cvs-all mailing lists. This is not just a good idea, it's essential. If you aren't on freebsd-current, you won't see the comments that people are making about the current state of the system and thus will probably end up stumbling over a lot of problems that others have already found and solved. Even more importantly, you will miss out on potentially critical information (e.g. ``Yo, Everybody! Before you rebuild /usr/src, you must rebuild the kernel or your system will crash horribly!"). The cvs-all mailing list will allow you to see the commit log entry for each change as it's made along with any pertinent information on possible side-effects. To join these lists, send mail to `majordomo@FreeBSD.ORG' and say: subscribe current subscribe cvs-all In the body of your message. Optionally, you can also say `help' and Majordomo will send you full help on how to subscribe and unsubscribe to the various other mailing lists we support. Grab the sources from ftp.FreeBSD.ORG. You can do this in three ways: Using the CTM facility described below. Unless you have a good TCP/IP connection at a flat rate, this is the way to do it. Use the CMU `sup' program (Software Update Protocol), also described below. This is the second most recommended method, since it allows you to grab the entire collection once and then only what's changed from then on. Many people run sup from cron and keep their sources up-to-date automatically. Use ftp. The source tree for FreeBSD-current is always "exported" on: ftp.FreeBSD.ORG:~ftp/pub/FreeBSD/FreeBSD-current We use `wu-ftpd' which allows compressed/tar'd grabbing of whole trees. e.g. you see: usr.bin/lex You can do: ftp> cd usr.bin ftp> get lex.tar.Z And it will get the whole directory for you as a compressed tar file. Essentially, if you need rapid on-demand access to the source and communications bandwidth is not a consideration, use sup or ftp. Otherwise, use CTM. If you're grabbing the sources to run, and not just look at, then grab all of current, not just selected portions. The reason for this is that various parts of the source depend on updates elsewhere, and trying to compile just a subset is almost guaranteed to get you into trouble. Before compiling current, read the Makefile in /usr/src carefully. You should at least run a `make world' the first time through as part of the upgrading process. Reading freebsd-hackers will keep you up-to-date on other bootstrapping procedures that sometimes become necessary as we move towards the next release. Be active! If you're running FreeBSD-current, we want to know what you have to say about it, especially if you have suggestions for enhancements or bug fixes. Suggestions with accompanying code are received most enthusiastically!
