FreeBSD image

[nschonni]

Maybe there is something that is incompatible, but a FreeBSD image would help the node-sass project. We build binaries for that platform, but having a common baseline from Node would be super helpful.

Docker uses the host kernel to run stuff, as explained here:

http://rhelblog.redhat.com/2015/07/29/architecting-containers-part-1-user-space-vs-kernel-space/

So you cannot run a FreeBSD kernel "in the container".

Options include:

• trying to run FreeBSD user land on top of the Linux kernel (like Debian tried) but there is no ABI compatibility there.
• have FreeBSD ABI emulation on Linux (not sure it exists)
• use qemu user land emulation to run FreeBSD code
• cross compile for FreeBSD using clang

All of them seem to be much more complicated than having a FreeBSD box and build things there using e.g. Poudriere.

I'm inclined to close this out since it doesn't seem like something we can solve with a Docker image.

If no one objects I'll close this out later today.

Yeah, did some more reading and did find there is compatibility now, but until there is an official image I think this should be closed.
