Not really. The actual thing is, linuxulator is a Linux kernel running as a FreeBSD kernel module. The only thing FreeBSD kernel do is to identify the Linux program and to pass it to the Linux kernel. To the Linux programs inside a GNU chroot enviroment, they think they are running inside a Linux box and actually they are running inside a Linux box.
Are you sure about that? I was under the impression that it was a fairly thin emulation layer on top of the FreeBSD kernel. Has something changed?
To Linux program, there is no "emulation layer". This technology should be called "extended ELF lookup table", and has nothing to do with emulation.
It's not emulation in the narrow sense that vmware is emulation and wine isn't, but it certainly is emulation within the normal sense or the word. My dictionary defines emulate as "imitate zealously".
It's not emulation, in fact it's much more like wine. We have traditionally referred to it as "Linux binary compatibility" rather then emulation, since the Linux syscalls are actually implemented by the FreeBSD kernel.
But what I was getting at was the statement "linuxulator is a Linux kernel running as a FreeBSD kernel module" which I'm guessing now you didn't mean literally.
That's not true in the sense that it's a separate process, but it is true in a sense, see above.
