Hi
Note: you can drop me in the CC, I'm following the bug report via the
debian-www mailing list.

No, as you note below.

This can be done in the meanwhile in the test_cvs2git repo:

https://salsa.debian.org/webmaster-team/webwml/test_webwml_cvs2git

I've just added there the file cvs-revisions which was generated by the
cvs2git script during the conversion.

I have no opinion on this. Frankly I don't know what to do if we cannot
get the new workflow working when Alioth is shutdown or the cvs service
stopped.
Maybe we can try to setup a CVS repo in other place, or ask translators
to manually keep track of the translation-check line (even when the
dashboards are not working).

I think the next steps are:
1.- Writing a script to get all the files with translation-check line to
be updated using the corresponding git hash. (This can be done in the
test_webwml_cvs2git repo, and when we do the authentic migration we run
it again)
2.- Get the copypage.pl and the smart_change.pl scripts working with git
hashes.

Thanks!
