We could, but this complicates things. As it is now, it just doesn't mention (nor affect) the kernel config name at all, instead using KERNFAST as a binary flag. Also, trying to actually set the kernel name using KERNFAST would probably result in failed build, since for KERNFAST to work, you need to have previously completed a non-KERNFAST build with that config name. _______________________________________________ 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"
