# Beware: irqbalance tries to read and handle environment variables
# directly itself, but since start-stop-daemon clears the env
# we convert the variables to commandline arguments here...
# (Note: in the daemon an option is enabled even if its set to
# e.g. the empty string or 0 or whatever. To disable it should not
# be exported at all!)
# Warning: this will need to be maintained and updated on upgrades
# to new upstream release which might introduce new ones!
