This would not drop it, but it would mean that you can't necessarily kldload /boot/kernel.GENERIC/foo.ko while running some other kernel. > Also, we should not use /usr/local/sys/modules/<foo> as /usr/local > can be inaccessible for the loader.

You misunderstand. /usr/local/sys/modules would hold module sources so that they can be recompiled when building a kernel without having to rebuild the package or reinstall the package. Binary modules would continue to be installed in /boot/modules. -- John Baldwin _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
