[lttng-dev] Explicit setting of UUID with ctf writer

[Rocky Dunlap]

Phil,

This relates to my previous question about multi-process tracing. The
workaround I am attempting is to have each process write its own trace with
a single stream, but then to pull all the stream files together into a
single trace with one metadata file. For this reason the uuids would need
to match.

Do you think this will work?
