There is a getcwd(), but in FreeBSD at least it's a library function,
not a system call. Perhaps the library has to look up mount points.
du (in at least FreeBSD, Gnu coreutils, busybox) also has an option to
not traverse mount points, making 2/5 of programs featuring directory
recursion also have an option to not traverse mount points. The others
are ls, grep, and diff.
