BTW, what are the differences? - a possible call to setuid/setgid, and their values in the config if the service is not to be started as root? - the default values of the config file and log file(s)? possibly some service-specific values in the config whose default value depend on the user/group under which the service is running? maybe the user/group should be a mandatory value under the hood, and the se= rvice code should dispatch on their values and the current effective user/g= roup id, and act accordingly? what am i missing? --=20 =E2=80=A2 attila lendvai =E2=80=A2 PGP: 963F 5D5F 45C7 DFCD 0A39 -- =E2=80=9CThe moral law is one of the basic laws of the universe.
