Re: Safe to just rebuild kernel after cvsuping src?
Kevin D. Kinsey, DaleCo, S.P. said: It's really a question for the programmers, and it's likely that whatever they say will include a lot of disclaimers and warnings. I once got kernel and world a lil' out of sync, and had things running apparently normally. However, top(1) broken; when I asked the list what was up, someone else with experience was able to determine the problem immediately. In short, it's probably not a good idea unless one can determine that relatively nothing has changed in the source since the other part (kernel or world) was built. Looking at CVS, you don't see much completely idle time. And, unless you are aware of every bit of code that might have changed, it's impossible (for me, Joe Average) to know what might break I'll keep that in mind, then.

(This is not to say you can't do it and have it work - been there, done that - but you're definitely increasing the odds of a problem.) I've been doing the opposite on some of my machines which run stable releases of FreeBSD. Is it relatively safe to build and install a slightly newer world without rebuilding the kernel? Were I to want to do this, I would (after updating the sources): 1) read /usr/src/UPDATING. If there is an entry that requires it (e,g, 20041102) or even implies it; then rebuild world. 2) following the directions in the Handbook rebuild the kernel only. Capture the output, and look for any complaints about missing symbols, etc. 3) Save the old kernel/kernel directory into a dated space. The install kernel target will save a copy ... but that gets overwritten if you have to build/again. 4) (optional) sacrifice black chicken to deity of choice (if any). 5) install new kernel and reboot. If sucessful, run mergemaster and reboot. 6) Test all first and second tier system functions and user applications. For this purpose, method of updating source code is a first-tier application.

Umm, umm, lol, yes I thought of this after I sent it, most of the updates are for userland and system tools, not the kernel, duh, sorry. I know everyone always says read the handbook but in this case it is very useful. Read the chapters on the FreeBSD kernel and also the chapter aptly named The Cutting Edge Regards, Ben Been there done that and I did it long time ago, this was just a moment of stupidity and not thinking before posting. I was in the middle of updating my sources when I had to make some changes to the kernel and rebuild it and I didn't have time or the desire rebuild world. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
