If your Open Source project requires significant work to install, work that would be easily scriptable by a competent software engineer, I'm not going to use it. The reason I'm not going to use it is because I'm going to assume you're either an incompetent software engineer, or the project is in unfinished beta state not useful for a production environment. Because a competent software engineer would have written those scripts if the product was in a finished production-ready state. Meaning you're either incompetent, or your product is a toy of use for personal entertainment only.
Is this a fair assessment on my part? Probably not. But this is what 20 years of experience has taught me. Ignore that at your peril.
