NOTE: Slightly OT, but figured it was worth the post.
As a side-note, the config-file will be "cleaned up" before being embedded into
the kernel. Meaning "config -x `sysctl -n kern.bootfile`" will rarely ever
match the config that was used to generate the kernel in the first place.
Specifically, comments are removed, and if you've nested configs using the
"include" statement, redundant and/or conflicting directives will be
consolidated.
If you instead wish to embed the kernel config AS-IS, comments and structure
remaining in-tact, you should instead:
cd /sys/ARCH/conf
config -C -g CONFIG
NOTE: `/sys' ought to be a symbolic link to `/usr/src/sys'
NOTE: ARCH is to be replaced with something like "i386", "amd64", etc.
NOTE: CONFIG is to be replaced with something like "GENERIC", "PAE",
"MYCUSTOMKERNELCONFIG", etc.
Then one simply does the following to compile the kernel:
cd ../../compile/CONFIG
make depend
make
BUT... then again not everybody:
a. compiles their own custom kernels
b. uses a custom config
c. needs to be able to extract the config verbatim from the compiled kernel
YNMV (Your Needs May Vary).
