Has similar work been done in FreeBSD been done? This would be a nice feature in 5.0-CURRENT. We had SecureBSD, and the IBM port of propolice, but both projects appear to be defunct at present. If we can integrate MAC into the kernel, why not port over OpenBSD's rebasing implementation from /src/s

You have to understand that some of these people know a ton of unix because for as long as I have been alive they have been working, hacking on Unix.

Silly question regarding x86-64

Hello, I have a very silly (because real hardware isn't yet ready) question to x86-64 support. According to the docs, the first implementation of x86-64 will use PAE to map 48 bit address space to 40 bit, which is 128 GB. Will FreeBSD support that 40 bit addressing or it will be similar to the al
