Well, work has been done to make it so that different runtimes will work -
e.g. there's a CRuntime_Glibc and a CRuntime_Bionic. So, druntime is a lot
better off than just linux vs FreeBSD vs whatever. But it wouldn't surprise
me in the least if someone using something like Debian GNU/kFreeBSD would
find some problems with what we currently have.
