It could work. It can also easily break things with newer kernel too, I can remember many cases. /sbin/ipfw, ps, ifconfig, netstat, top, killall and some important others are not guaranteed to run with newer kernel. I still run FreeBSD 4.11-STABLE inside 11.2-STABLE jail and that's why I know this. > And why a subset?

OO. We could still add the whole bunch of needed .h files from /usr/src/sys/ there. _______________________________________________ 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"
