Hello,

The environment variable FIRST_ARG is considered as a poor interface provided
by the systemd rpm macros.

This was probably required because of the %service_* rpm macros were playing
tricks with the shell positional parameters. 

This was bad practice and error prones so we would like to remove FIRST_ARG
support entirely and hence it should be safe to assume that positional
parameters remains unchanged after any rpm macro calls.

However it seems that net-snmp uses FIRST_ARG for a different purpose... would
it be possible to implement that differently so FIRST_ARG is no longer used ?

Thanks
