pip freeze equivalent - command to print commit id of all projects

[frdeso]

Similar to the pip freeze.

It should print everything you need to know to recreate the exact same environment.
Maybe in the form of a command line that can be copy-pasted directly or some MI format that can be passed to vlttng.

If you do:

vlttng ... -v

then the effective profile is printed at the beginning of the output. This is enough to recreate the exact same virtual environment afterwards:

vlttng -p ./effective-profile.yml

Is this enough? Perhaps we could generate it as $VLTTNG/profile.yml. I'm not sure to understand the use case here, but I'm curious.

I was thinking of something that can be run at any time when the env is active.
vlttng would iterate over all the trees and create a profile with the commit IDs, URLs and config options of all project.

It would be a simple way for me to send you the exact configuration(frozen in time by commit IDs) that triggers a bug for example.
