As previously reported on the list, make sure you are running bash as 
your sh equivalent. The script (/etc/init.d/instsvcdrv) has several 
"bashism" and does not play well with dash, ash etc.


sh --version should tell you what you are running.

If it is NOT bash, the exact mechanism to use bash as the sh replacement 
is a matter of preference, the quickest is a soft link in /bin (mv 
/bin/sh /bin/bad-sh; ln -s /bin/bash /bin/sh) or the debian way 
dpkg-reconfigure bash.

If it is bash, let us knw what the real problem was.
