Hi Stephane, Below details i get from installer log when the script is included with the package. I tried modifying the dist file but to no avail. Any suggestions to get it running?

Hi Stephane,

Thanks for explanation. But if i include only memory requirement, it does not create any dist file. When I add Disk space requirement and include a preflight script along with the package it fails while installing. If I do not include the script it works fine or vice versa, If i include script and removed disk space requirement it works. I think it's something to do with the dist file. I have pasted just a line from the dist file, I tried changing it though. But i guess you might help me out .

options customize="never" allow-external-scripts="no" ( Script fails because of this ? ) Do i need to  allow external scripts to run?

...

rootVolumeOnly="true"/>    <installation-check script="pm_install_check();"/>    <volume-check script="pm_volume_check();"/>

If you're calling an external shell script from the installation- or volume-check scripts, yes you need to allow external scripts. Even if the shell script ends up being embedded in the distribution.
