+ Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
+ and renamed from .symbols to .debug. This reduces the size requirements
+ on the boot partition or file system and provides consistency with
+ userland debug files.

+ Developers wishing to maintain the historical behavior of installing
+ debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
