It would be valuable if building a system on an exec-protected src file system would continue to be possible. Not sure if the /usr/src/contrib/netbsd-tests/lib/libc/net/gen_ether_subr is the only such new command breaking the build. Anyway, a simple workaround is to run shell from a command line instead of as a shebang, i.e.: # /bin/sh /usr/src/contrib/netbsd-tests/lib/libc/net/gen_ether_subr instead of: # /usr/src/contrib/netbsd-tests/lib/libc/net/gen_ether_subr Mark
