And here's the implementation I've been using for a very long time with the
X maintainer scripts, which is simpler than yours but requires perl.  (I
think Joey Hess wrote this.)

readlink () {
  # perl kludge until readlink(1) from tetex-bin is moved into an essential package
  # returns what symlink actually points to
  perl -e '$l = shift; exit 1 unless -l $l; $r = readlink $l; exit 1 unless $r; print "$r\n"' $1;
}

Not sure we want libc6 pre-depending on perl, though ( >>shudder<< ), so
something written in pure sh might be the way to go.
