There's a bunch of one-liners and small scripts on the internet which almost work with DTrace 2.0 but need a little bit of porting.

@kvanhees has answered my questions on a bunch of them and I've tried to document common issues so far at https://wiki.gentoo.org/wiki/DTrace#Online_examples_not_working. One of them was #79 (comment).

So far, we have:

  • execveat_common which should be replaced with the more generic entrypoint proc:::exec
  • open being vulnerable to libc implementation details

We should document other known cases which are known (but not to me) and list the new, idiomatic way of doing the $THING.

(Or maybe it really is just those I listed on the Gentoo wiki and I'm extrapolating too far?)
