FFS. Damned CVS. Here is the actual commit text: Historically (prior to supporting the KERNEL_DIR build option), the boot-commands ``boot file'' and ``boot /file'' were equivalent and attempted to execute the same set of files. (In the boot-loader, all path (filename) lookups start at the root directory whether or not a leading slash is present.) However, with the recent addition of support for the KERNEL_DIR option, the leading slash character resulted in skipping the attempt to load /file/kernel and /file/kernel.gz, and thus the boot loader will not attempt to boot from a new KERNEL_DIR environment if the leading slash is present. This commit restores attempting to load these files, thus making these two boot-commands once again equivalent in both legacy and KERNEL_DIR environments.. Changes were tested on both i386 (biosboot/qemu) and amd64 (both biosboot/qemu and efiboot/bare-metal). Correct behavior was observed using the filenames printed by a preexisting printf(). The output from ``boot'' commands without arguments was also confirmed to meet expectations, and commands other than ``boot'' continued to work as expected. As discussed on tech-kern, port-i386, and port-amd64 mailing lists. The more extensive documentation requested by riastradh@ should have been dealt with more than five years ago with the initial KERNEL_DIR commit; this commit doesn't pretend to meet that request. As noted by kre@, the changes being made here are minor/trivial and highly unlikely to break anything. These changes only affect booting in new KERNEL_DIR environments; "legacy" environments are not affected.
