It would be nice to have an option -- or do by default -- the logging of stap options as they're being invoked by stap-serverd, into /var/log/stap-server/log. (A complication is that stapargv[] could contain large pieces of script if invoked with stap -e '....', but maybe that's fine to log too. -e scripts tend to be small.)
Done in commit: 40ae3a752d7f7593c5db171756e82e48b18ff66b Logging the client's options is now done by default.
