Bootstrap script deploys app using yum, how can I deploy on Ubuntu

I am deploying an application that has a bootstrap script, which installs a bunch of packages using yum. However, I am deploying on Ubuntu Maverick. Does is make sense to upgrade the script to use apt-get instead. I installed yum on ubuntu, but not sure how to configure repositories开发者_JAVA百科 and such, plus I am not sure if continuing with yum is the right approach.

It's most likely best to upgrade the script to use apt-get unless it is a really long script. Most users will not want to go through the hassel of installing yum.
