Bug#767253: Acknowledgement (Please provide hashes for uncompressed Translation-* )

[Michael Vogt <mvo@debian.org>]

Hi,

I had a quick look at the debian-cd scripts and something like the
attached (and totally untested) patch is probably sufficient. 

The idea is that we keep both Translation-* and Translation-*.gz
around, then generate the Release file with the hashes and then remove
the uncompressed files from the CD. Apt should really not need the
uncompressed files on the cdrom, but it does need them in the Release
file for the verification.

Sorry that I have not tested this, I'm not familiar with the cd
building and I couldn't find unittests. But I'm happy to dig into it
if needed.

Thanks for your consideration,
 Michael
