I tried to update the 4.6.2 and failed, but from the local 2600 meeting Friday, it was MY error, not the software.
There is a page on updating the kernel on freebsd.org (lemme see if I got a book mark or the page in cache) that gives you the 4 basic steps in upgrading kernels. What I missed was that BSD is NOT LIKE LINUX! The kernel is tied VERY closely to binutils and must all be upgraded together. I wanted a new kernel and ports snapshot. Needless to say that that is about 40 percent of what was needed ;D
Ill post back with the link. Its in the handbook online (if you are able to get the data before me)
Start reading here if I recall correctly. I may have gone too far, but that is the beginning of the chapter, and does detail eventually all that is needed.
