Indeed - changing things to be 'bash script' instead of the current 'bash -c 
script' would make the use of alternative interpreters harder.  But it does not 
make it impossible; you can always do:

#!/bin/sh
/bin/awk <<\EOF
...
EOF

instead of

#!/bin/awk
...

For that matter, are there any postinstall scripts currently relying on a 
different interpreter?  If not, then I'm in favor of the idea of changing 
setup.exe to be immune to the execute bit on postinstall scripts, at the 
expense of making postinstall scripts locked into bash (at least, as the 
initial interpreter).
