[lttng-dev] babeltrace CTF -> Text -> CTF

[Alexandre Montplaisir]

Hi,

babeltrace-log is just a small tool that "wraps" a text file in CTF. It 
is not a lossless conversion back to CTF format from a babeltrace 
output. To do that, you would need to do something like:
$ babeltrace -i text -o ctf ...
but that is not supported yet.

So it's expected that the initial CTF file and the one after conversion 
are not exactly the same. Everything will get dumped into the payload, 
among other things.

Cheers,
Alexandre
