The config file can specify upper/lower limits, variables, settings,
etc, etc. But in the end, some executable somewhere is going to have to
parse the config file, check the actual environment, and decide whether
or not to launch the service, and with what parameters.
Note also that many open source programs are multiplatform. I.e. they
run on FreeDOS with DJGPP, multiple flavours of Windows, multiple BSDs
(including Apple), linux, and multiple commercial unix flavours. Do you
really want to throw multiple platform-specific IFDEFs into the program
code to allow the services to do the appropriate platform-specific
initialization? Isn't it be easier to move the service setup out of the
main service, and let the maintainers of the specific platforms figure
it out?
One last question. Let's go back in time 20 years, and assume that
you're the maintainer for a program that runs as a service. A small
handfull of end-users come along. They're running a "hobby OS" that
fits on a couple floppies. Said "hobby OS" has been cobbled together by
a university student. Would you...
* download that university student's hobby OS, and install it
* throw in a bunch of additional IFDEF initialization code in your program
* test and debug the program to make sure it runs under that OS
