I believe service is just a front end to those scripts, so I presume 
that, by "service shell scripts" he is referring to those scripts.  The 
problem he is having is that they probably source files (bash . command) 
files containing shell variable definitions from the master 
configuration directory, maintained by the, typically GUI, configuration 
tools.  I suspect he hasn't realised that is is sourcing thesse files.

Note that not all Linux distributions use this style of startup script, 
some are based on a more historical style of /etc/rc.
