buildworld every time?

Been playing with 7.1 now for a bit, seem to be getting the hang of most of it. And really happy about the forum here. Great community effort of assisting people. My hat off to the community.

I have been reading a great deal of documentation on building custom kernels. Everything I have been reading tells me these steps:

buildworld
buildkernel
installkernel
boot into single user mode with new kernel
installworld
if anything fails along the way start over.

That last line tells me that I need to start from buildworld if a kernel fails to build. is that necessary?

Also, if my source tree has not changed, at all, do I need to buildworld each and every time I wish to rebuild a kernel? lets say I am doing a bit of kernel testing, and just wish to remove a few options or add a few options to my kernel.

Hoping the answer is as easy as I think it might be. And a great big thank you for reading and replying.

Cheers
Murias

No, if a kernel really fails you won't be able to boot. If you're just missing some functionality you can just rebuild the kernel without the buildworld.

Once world and kernel are in sync (version wise) you can rebuild/reinstall the kernel separately without problems.
