Hi, I intend to remove the compat-FreeBSD support from the system. It has a limited interest since no major proprietary software is developed on FreeBSD; if one were, it would certainly be available on Linux, and we have full compatibility support for that.
You will also notice, after reading the code a bit, that our FreeBSD layer is really poor: many syscalls are missing, the translation is not efficient, and the layer is only available on i386. Recent FreeBSD-10 binaries often crash. Recently we found two enormous bugs so obvious and harmful that we should normally have received a bug report from a user somewhere. We didn't, which means that in 6 years nobody tested compat-FreeBSD - "nobody" being the developers and the users. Clearly, we should not waste time and energy on something that simply does not work. compat-FreeBSD could give the impression NetBSD has a reliable way to execute FreeBSD binaries, which is far from being the case. This is what motivates my proposal. Ok?
