This part of the output is curious:

The marked line tests if block-tap is executable, and then suddenly jumps to 
another script, which is doing a remove.

1) Is block-tap indeed marked as executable? My SuSE 10.3 system doesn't even 
have a block-tap, so I'm not sure what package that comes from. What is the 
output of 'rpm -q --whatprovides /etc/xen/scripts/block-tap'? If you don't 
have it either, try 'yum install /etc/xen/scripts/block-tap'.

2) Can you verify what script the rest of the output after the flagged line is 
coming from?
