we have staged/production setup and would like to test all updates on staging before deploying them on production.

Ideally, we would like to pin the exact state of which packages are installed on staging, e.g. by date when installed, so that we get exactly the same on production.

In Debian there is snapshot.debian.org which could be used to do so.

Is there some way to do so in Devuan?

Further questions in respect to differences between Debian and Devuan:

- Are the security updates, except of rebuilds as necessary, identical to Debian?
- Are security updates also collected in point releases like in Debian?

best regards,
Markus
