Firstly, FreeBSD maintains a backwards compatible kABI (with the exception of programs that hunt around in kernel memory). We also use symbol versioning on the libc. so depending on what you want to do. the answer may be useful to you or not. Basically any binary should continue to run on a newer kernel, even if the syscalls change, because we should still support the old abi. tell us more about what you need and we can be more specific. I have run Freebsd 1.1 binaries on a Freebsd 8 system, in fact I have done a system build in a freebsd 1.1 chroot on an 8 system. I haven't tried it on 9 or 10 but I'd expect it to work.. > > > > Thanks, > > Venkat. > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" > >
