Author: emaste Date: Thu Sep 24 16:55:22 2015 New Revision: 288176 URL: https://svnweb.freebsd.org/changeset/base/288176
Log: Install kernel debug data under /usr/lib/debug This avoids needing a large boot partition / file system in order to accommodate multiple kernels, and provides consistency with userland debug. This also simplifies the process of moving kernel debug files to a separate package and installing them on demand. In addition, change kernel debug file extension to .debug, to match userland debug files. When using the supported kernel installation method the /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) as is done with /boot/kernel. Developers wishing to maintain the historical behavior of installing debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
