Although I understand the question, I will not take the time to
re-evaluate a design that involves CTF 1.8. I'm currently in a "quick
fixes only" mode for this format, with the sole aim of keeping existing
scenarios working.

We're currently investigating the status of CTF 2 support in Trace

Yes we know. Have a look at make_lttng_trace_path_rel().

`create-lttng-index` would be another hint, but the trace environment
has been good enough so far.
