Yepp, though I would reorder it a bit, maybe more like

ustctl create-trace nils_trace
ustctl enable-marker nils_trace sendmsg_marker
ustctl bufsize nils_trace ust 2MB

or something like that...

But I have to admit I've been working with switches lately which all  
have nice custom CLI's with tab based help and command expansion and  
stuff so I'm a bit spoiled.
