I have NOT implemented a single bit of native syscalls API and when I am going to do it it will be 100% posix API (minus bugs ;) ) we can commit this in two phases: phase I: kern_fooat() + linux stuff phase II: native fbsd syscalls I hope to resolve all the issues Eric raised over the weekend (hopefully) and then it only needs a review(er) + a commiter I definitely want this in for 7.0R. does this sound good to you? roman
