possible repercussions for RB tooling of Debian migrating from zlib to zlib-ng

[Fay Stegerman]

Hi,

I wrote about issues encountered with "unreproducible zlib/deflate compression
in ZIP/APK files" [1] before.  Debian is apparently considering migrating from
zlib to zlib-ng [2], which could affect RB: assuming zlib-ng output is properly
deterministic for the same version it should not affect reproducibility of
Debian packages themselves, but it could affect using a Debian base system to
reproduce other software (like Android APKs).
