Not sure I understand the motivation for the "cd" invocations here --
just making a symlink shouldn't need that, right?

| ln -s ../proc/self/mounts "$TARGET/etc/mtab"

(Since a symlink is essentially just a special-typed plain text file
and "ln -s" doesn't really care about the working directory except for
interpreting the final target argument if it's relative.)
