Apt reproducible installs

[cen]

Are there any efforts underway for apt to do reproducible installs?

I am trying to build bit-by-bit identical OCI images and it feels like I 
am doing a lot of hacks and workarounds to get things working

and in reality it should be apt that needs to evolve and support 
reproducible installs.

Running apt in "reproducible mode" could automatically:

1. Switch to snapshots repo according to SOURCE_DATE_EPOCH

2. Disable logging and caching or at least clean after

3. Use SOURCE_DATE_EPOCH on all installed files (either natively or 
automatically using libfaketime)

4. ???

5. Profit!


Just throwing ideas out there but the current situation when I need half 
of my Dockerfile to be scripts forcing apt to play nicely is not ideal.
