How to get source for kernel, world to match currently running kernel?

[Time2IPL]

Apologies in advance for this question; I have a feeling that I'm probably missing something or ??? here.

I'm currently running 8.0-RELEASE-p2, which I installed from the 8.0-RELEASE DVD, and have been keeping up to date with freebsd-update (I've been keeping my ports current w portsnap). Everything seems to be working fine.

However, it occurred to me yesterday when I went to build the kernel and "world" that I have no idea whether the sources in /usr/bin, /usr/lib, etc. match the currently running kernel, etc. - does "freebsd-update" keep those in sync? or are they the same as they were when I first installed the system?

I read through the handbook, etc., but I'm just not getting how to determine whether the sources I have are current and/or download ones that match a given release and patchlevel.

Thanks
Larry

Why on earth would you build the world and kernel when you're using freebsd-update? The whole point of freebsd-update is not having to build the world and kernel, and just installing binary updates to world and kernel.

If you want to build everything yourself, just use csup(8) and track -RELEASE or -STABLE. Now you're just doing it twice.

Also, you seem to have a funny idea of "sources". The source code is kept in /usr/src. /usr/bin contains binaries and /usr/lib contains libraries, both are compiled from source.

And to be more concise: if you instruct freebsd-update (through freebsd-update.conf) to sync 'src', the source tree in /usr/src will be the same source tree that built the binaries freebsd-update is installing. Building and installing it all over again will keep your room warmer, but not add any value to the operating system.

I had a feeling there was a better way to ask this...

They're two separate machines. I'm trying to bring an old device driver up to date and before I started doing anything I wanted to make sure I was running the exact same kernel, etc., on both machines. Only with one built from sources and one not.

Sorry for that]

Ah, perfect. That's exactly what I was trying to figure out and wasn't 100% on. Thanks.

At some point in the past - I don't recall whether it was with FreeBSD or another OS - I started off a similar effort with a source tree that was close to what was being released in binary form but not close enough to spare me from a lot of wasted effort. I was trying to avoid a similar mess.
