I am also a Linux convert and have had great success with FreeBSD over the past several years. I use the freebsd-update utility (http://www.freebsd.org/cgi/man.cgi?query=freebsd-update&apropos=0&sektion=0&manpath=FreeBSD+7.0-RELEASE&format=html) to perform binary upgrades on the servers that I manage. Be aware that it only supports upgrading GENERIC kernels. If you have a custom kernel, read the bottom of this post for information about how freebsd-update handles that: http://www.mavetju.org/mail/view_message.php?list=freebsd-stable&id=2642739 You can use freebsd-update to upgrade FreeBSD minor releases as well as major releases. Check out these blog postings for more information: http://www.daemonology.net/blog/2007-11-10-freebsd-minor-version-upgrade.html http://www.daemonology.net/blog/2007-11-11-freebsd-major-version-upgrade.html Best of luck, and post back to this mailing list with additional questions that you might have.

No, you need to do two things: 1) copy /usr/share/examples/cvsup/standard-supfile somewhere, and edit it to fetch the right version of the sources from the right server. If you want to get exactly the version you have installed, you only need to change the server. Look for the line starting with "*default host=" and find a host near you from this page: http://www.freebsd.org/doc/en/books/handbook/cvsup.html 2) run "csup your-supfile" - this will fetch kernel and base system sources (note that utilities like "ls", "top", "sendmail" etc. are not ports in FreeBSD; also note that the cvsup client integrated into the base system in all recent versions of FreeBSD is "csup" not "cvsup". > How do I apply this new code? Read here: http://www.freebsd.org/doc/en/books/handbook/kernelconfig.html and here:http://www.freebsd.org/doc/en/books/handbook/makeworld.html In short: # cd /usr/src # make buildworld && make kernel && make installworld && mergemaster -U && reboot signature.asc Description: OpenPGP digital signature

No. FreeBSD is released as a complete operating system and not just a kernel with distributions arround it. If you want to run FreeBSD you will have to run the operating system. But of course you can get the code you want by cvs. > > I'm curious if I could do something like in was doing in Linux before > linux 2.6 was officially released where I had the choice to run a 2.6 > test kernel or load a 2.4 kernel so I could try out some of the new > features without dedicating my system to running it full time in case > of any stability problems.

You have the choice to run -RELEASE, -STABLE or -CURRENT. What you are looking for is -CURRENT. There you can test anything you want and take part in development. For production use you should run RELEASE and you can also run a second installation on your test machine like -STABLE. For more info see the FreeBSD Hnadbook, especiallay: http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/current-stable.html > > Also, are there many patches for trying out new features like improving > latency on a system or trying out a new scheduler? (These are just > examples I took from linux.) Indeed, there is currently a new scheduler in FreeBSD. You can choose it by compiling your own customized kernel.

But you ave a userland emulation. -Harry pgp0.pgp Description: signature
