run.sh doesn't properly resolve symbolic link

Continuum 1.1-beta-3 installed in my linux box and configured to start automatically as descibed in http://maven.apache.org/continuum/guides/mini/guide-linux-boot.html.
At startup, I've got the following message :

/etc/rc2.d/S80continuum: line 62: cd: ../init.d/../..: No such file or directory

This problem seems very similar to MAVEN-1532, so I tried replacing

if expr "$link" : '.*/.*' > /dev/null; then

with

if expr "$link" : '/.*' > /dev/null; then

in run.sh, and it's working fine.
