Thanks Miroslav Lachman for the reply with the correct sizes for GENERIC
kernels.
Change FAQ 8.3 Why is my kernel so big?
Nowadays kernels are compiled in /debug mode by default/. Kernels built
in debug mode contain many symbols that are used for debugging, thus
greatly increasing the size of the kernel. Note that there will be
little or no performance decrease from running a debug kernel, and it is
useful in case of a system panic.
However....
I think that debug symbols are in another files (*.symbols)
FreeBSD 8.3-RELEASE amd64 GENERIC
> ls -lh /boot/kernel/kernel*
-r-xr-xr-x 1 root wheel 12M May 8 2012 /boot/kernel/kernel
-r-xr-xr-x 1 root wheel 50M May 8 2012 /boot/kernel/kernel.symbols
So a kernel alone has 12MB, with debug symbols 62MB (12+50).
And all *.symbols files can be deleted (if more space on /boot is needed)
I don't know how it should be mentioned in FAQ.
