The linux emulation code has since been fixed to try harder, as Linux applications expect it to. I'm not sure that people would be in favour of making procfs try harder, as procfs doesn't even have to be mounted for most things in FreeBSD now. If you did want to try and fix it, then the place to start looking would be at the Linux emulation getcwd code in /usr/src/sys/compat/linux/linux_getcwd.c. David.
