FreeBSD developer Colin Percival announced on his blog today that FreeBSD 9-CURRENT now runs on Amazon EC2. A number of FreeBSD developers have contributed to this project. "There are some caveats to this. First, at the moment only FreeBSD 9.0-CURRENT can run under EC2; I haven't merged bug fixes back to the stable branches. Second, at the moment FreeBSD only runs on t1.micro instances, for reasons I can't discuss (NDA) but hope will be resolved soon. Third, this code hasn't received very much testing and is almost certain to have more serious bugs, so it should be approached as an experimental, not-ready-for-production-use system for now. "
