Don't forget that most Unix-like operating systems and Linux distributions use package managers, typically one installs the package then configures some number of config files to get the thing up and running. Some are working right after the install. The problem with packaging web applications is that most don't take into consideration things like File System Hierarchies and are very difficult to package. If you have any sort of application and want it to be easy to install, make it easy to package (even closed source apps can benefit.) or package it yourself. Anytime I have to install some software (AWS' agents such as inspector and cloudwatch are particularly bad about this) and I have to extract some tarball or curl into `sh` I cringe. RPM/Apt/etc is right there, ready for you to use! Signature verification, config file handling, etc!
