Author: bz Date: Tue Oct 30 15:46:30 2018 New Revision: 339922 URL: https://svnweb.freebsd.org/changeset/base/339922 Log: Introduce an EXPERIMENTAL option for both src.conf(5) and the kernel. In the last decade(s) we have seen both short term or long term projects committed to the tree which were considered or even marked "experimental". While out-of-tree development has become easier than it used to be in CVS times, there still is a need to have the code shipping with HEAD but not enabled by default. While people may think about VIMAGE as one of the recent larger, long term projects, early protocol implementations (before they are standardised) are others. (Free)BSD historically was one of the operating systems which would have running code at early stages and help develop and influence standardisation and the industry. Give developers an opportunity to be more pro-active for early adoption or running large scale code changes stumbling over each others but not the user's feet. I have not added the option to NOTES in order to avoid breaking supported option builds, which require constant compile testing.
