Author: kevans Date: Thu Apr 30 02:50:58 2020 New Revision: 360486 URL: https://svnweb.freebsd.org/changeset/base/360486 Log: loader.conf(5): document that loader_conf_files may be clobbered A future change in lualoader may take some liberties with the loader_conf_files in the name of efficiency; namely, it may start omitting it from the loader environment entirely so that it doesn't need to worry about maintaining any specific value. This variable has historically been incredibly volatile anyways, as it may get set to completely different values in any given configuration file to trigger a load of more files. Document now that we may not maintain it in the future, but perhaps we'll reserve the right to change our minds and eventually formally export all of the loader configuration files that were read using this variable.
