Currently,
readlink -f foo
returns the null string if the target of foo does not exist. This behavior
differs from that of readlink in Debian woody. I hope that this will be
considered a bug because the new behavior is much less useful than the old
behavior. The new behavior can easily be emulated using the old readlink:
REALPATH="$(old-readlink -f "$FILE")"
[ -e "$REALPATH" ] || REALPATH=""
but the old behavior cannot easily be emulated using the new readlink.
With the new readlink there is no easy way to find out the ultimate
target of a symlink chain if the target happens not to exist.
