The "easiest" way is to roll your own installation. This has some other benefits, as it allows you to make any other pre-installation changes that you want. First thing you'll want is a good solid fast machine that you can do builds with, with a couple of GB of free disk space (so you can make multiple tries). You'll also want to install full source. Lastly, its not a bad idea to use an OS release at or around the version you're going to build. It helps remove some of those "unforseen" incompatibility issues. Then, install FreeBSD and get it running on a network that can talk to the outside world (aka the Internet) with a good-speed connection (28.8 will blow here. You'll need something like a T1 or cable modem, or better, etc). Next, review the use of CVS. You'll need to use this a bit to get things right. Next, use cvsup and /usr/share/examples/cvsup/cvs-supfile to pull down the CVS archive for the OS source. You'll need this to build a release. You'll need to make sure the file has src-all, ports-all, and doc-all defined (I believe that doc-all is missing from the stock one). Run CVS against it, and it should populate /usr/ncvs with all of the FreeBSD source from the dawn of time until present. Next, set the enviornment variable CVSROOT to /usr/ncvs. Then, go to a "working directory" and do a "cvs co -r RELEASENAME src". Replace RELEASENAME with whichever "stock" version you want (such as RELENG_2_2_7_RELEASE). If you're not sure whats available, cd in to /usr/ncvs/src, and more some of the files. The tags you can use should be up at the top. Once you've checked them out, branch the source tree, since you'll be making your own local changes that you'll want to keep. To do this, issue a "cvs tag -b YOURTAG src" from the aforementioned "working directory", so it will tag all of the src directory. YOURTAG can be replaced by anything you want, so long as its valid, and hasn't been used. Then, to change the boot disk, edit src/sys/i386/conf/GENERIC. The release process will strip out portions of this to minimalize it. Its in src/release/floppies/boot/floppy/Makefile (you'll probably want to edit both the one in /usr/src, and in your currently checked out copy, although the latter is the one that should be used). Otherwise, add the options you need to GENERIC. Once done, go back to your working directory, and "cvs commit src". It should check in all of your changes (and ask you to provide CVS comments for each). Once that is done, go to /usr/src/release, and edit the Makefile. Set BUILDNAME, CHROOTDIR, RELEASETAG and CVSROOT (not in the file) to proper values. Here are some of my values: BUILDNAME=2.2.X-CUSTOM (replace X with a release) CHROOTDIR=/usr/tmp/whereiwantmybuild (where the build will take place. Make SURE the directory exists!!!) RELEASETAG=YOURTAG (this is the CVS tag to use for getting the code. Make sure it matches what you "tagged" above) CVSROOT=/usr/ncvs (this matches the cvs-supfile you put together). Then, say "make release". It'll chug for awhile (depending on machine, its gone from a few hours to days). When its done, in CHROOTDIR, you should have builds for both a CDROM and a FTP site. If you dig down, and find the "floppies" section, you should find your new boot.flp. Note that the GENERIC kernel is also used for building the initial boot kernel. This will help you bring over CAM support in to the kernel that gets booted after install. If this is the only change, then you should be able to use the standard CD with the new boot floppy (although CAM support won't be in the kernel loaded by the CD), or you can burn your own release CD. Usually what I do when I build out a custom is to put all of the custom files on it, and then load the "remaining" files from the first CD (such as X, the packages, xperiment, etc) on to the new CD, allowing me a pretty "normal" Walnut Creek-type install. -Brian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
