Subject: [PATCH] systemctl: explicitly cast the constants to uint64_t
Otherwise under certain conditions `va_arg()` might get garbage instead
of the expected value, i.e.:
$ sudo build-o0/systemctl disable asdfasfaf
sd_bus_message_appendv: Got uint64_t: 0
Failed to disable unit: Unit file asdfasfaf.service does not exist.
$ sudo build-o1/systemctl disable asdfasfaf
sd_bus_message_appendv: Got uint64_t: 7954875719681572864
Failed to disable unit: Invalid argument
