The small-memory embedded systems most affected by this often don't use loader(8) at all, so tunables aren't an option, and sysctl may be too late. No reason it can't be a tunable as well, but it'll probably need to remain as a compile-time option too. -- Ian _______________________________________________ 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"
