+- Drop use of $FIRST_ARG in .spec
+
+  The use of $FIRST_ARG was probably required because of the
+  %service_* rpm macros were playing tricks with the shell positional
+  parameters. This is bad practice and error prones so let's assume
+  that no macros should do that anymore and hence it's safe to assume
+  that positional parameters remains unchanged after any rpm macro
+  call.
