If yes, then I'm open to suggestions :-) I'd remove the paragraph (4th from bottom of http://www.uk.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html) that says: "If you have not upgraded your source tree in any way (you have not run CVSup, CTM, or used anoncvs), then you should use the config, make depend, make, make install sequence." because it's somewhat confusing in the context of "If you are building a new kernel without updating the source code... you can use either procedure." further up the page, and I'm not really sure what it means: if I've just installed full source from a CD, but not 'upgraded' it, do I have to use the config procuedure? Obviously I don't, but that paragraph seems to imply that I do. Assuming Mike is right (and I tend to assume he is :-) about buildkernel using the installed toolchain if it can't find one in /usr/obj, the rest of the page makes perfect sense.

There's no reason not to use the kernel targets, as already discussed. The kernel targets does one thing different than the old way - it uses tools from /usr/obj if they are there, otherwise it uses the /usr tools. The reason for using the old one is that you may be able to skip some of the steps. In particular, if you're tweaking the sources, you can just do make and make install - no need to go through the config/depend steps. http://www.mired.org/consulting.html Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.

Scott, pardon my replying to your post to write to Darren. I missed Darren's initial post and I wanted to chime in adding my bits to your excellent explanation.

That sounds > > contradictory to me. What do you think? That's not exactly what the text says though. The text of the second paragraph where config(8) is referenced is: If you are upgrading to a version of FreeBSD below 4.0 you should use the old kernel build procedure. However, it is recommended that you use the new version of config(8), using a command line like this. # /usr/obj/usr/src/usr.sbin/config/config KERNELNAME This is true. Older FreeBSD versions, before FreeBSD 4.0-RELEASE, did not support the same make targets (buildworld, buildkernel) in the same manner. The writer of this part makes an attempt at supporting those with older releases too. If you have the sources of a newer FreeBSD version, then this paragraph doesn't apply to you. Does this clarification make it any clearer? Do you still think that the Handbook needs fixing?

What do you think? I may not be 100% right on this, but I believe the main difference is that 'make buildkernel' will build the kernel using the toolchain left in /usr/obj by a previous 'make buildworld', whereas the 'config' method uses the toolchain currently installed on your machine. That's why you should use buildkernel after a cvsup, to make sure your kernel is built against the same stuff your about to install with 'make installworld'. If you're just building a new kernel from the same sources, I guess either method would work, although you'd need to have the /usr/obj from your last buildworld still hanging around, so using config might be more convenient. Maybe that part of the handbook could stand a little clarification?

That section of the handbook explicitly says that you can use either procedure in that case.

Why should I use `config;make depend;make...` instead of `make kernel`when building from a stock source tree? (ref. Handbook sec. 9.3)
There are two sets of commands you can use to build a kernel in FreeBSD: "Procedure 1" is the old way: config, make depend, make, make install. "Procedure 2" is the make kernel sequence from makeworld. Section 9.3 of the Handbook says I should use procedure 1 if I haven't updated my source tree. I can understand then need to use procedure 2 if I've updated my source tree, but why shouldn't I use it with an unmodified tree?
