Author: gonzo Date: Wed May 15 18:56:42 2019 New Revision: 347629 URL: https://svnweb.freebsd.org/changeset/base/347629 Log: MFC r345550: Change default value of kern.bootfile to reflect reality In most cases kernel.bootfile is populated from the information provided by loader(8). There are certain scenarios when loader is not available, for instance when kernel is loaded by u-boot or some other BootROM directly. In this case the default value "/kernel" points to invalid location and breaks some functinality, like using installkernel on self-hosted system or dtrace's CTF lookup. This can be fixed by setting the value manually but the default that reflects correct location is better than default that points to invalid one. Current default was set around FreeBSD 1, when "/kernel" was the actual path. Transition to /boot/kernel/kernel happened circa FreeBSD 3.
