requirements to start a process under process management

Digging through how the template currently works, it looks like there are
several assumptions being made "up front" about what is required to launch
a program. The more I dig, the more I wonder how much of this could be
boiled down and condensed.

+ path of the program
+ path of any required libraries (if dynamically linked)
+ if a multi-part program, presence of all the other parts needed to start
or function
+ program-specific options as parameters (i.e. --some-option)
+ environment variables
+ a launcher (typically shell or a purpose-built program like execline)
+ a run directory to store settings, pid files (ick), sockets, etc.
+ configuration file(s)
+ presence of specific files, such as /dev entries, socket files, etc that
are not set by the program but assumed to be there
+ presence of specific directories (example: postgresql wants a data
directory for storing its tables)

Please point out anything that is missing. It helps to have a full picture
of what the expectations are, especially when they are "passed by oral
tradition" instead of written down somewhere. Thanks for any input in
