mount_ffs applies the mount system call and exits.

mount_mfs forks a background process that has the "memory disk" mapped
and that terminates when you umount.

While the chdir() isn't necessary, it avoids keeping the current
directory busy.

mount does a realpath() to resolve relative mount paths, not sure
since when..
