Bug#1108032: apt: Option to keep compressed files in the same format as used by the index target

Package: apt
Version: 3.0.2
Severity: wishlist

While working on 
https://salsa.debian.org/freexian-team/debusine/-/issues/945, I 
discovered that there appears to be no way to ask apt to store files in 
Dir::State::lists using the same compression format as is used by the 
index target it fetched them from.  You can set 
Acquire::GzipIndexes=true, but this just causes apt to recompress using 
what it thinks is the lowest-cost compressor.  If you know the 
compression format used by the index target in question in advance then 
you can set KeepCompressedAs on the relevant index target, but from a 
cold start you only know that once apt has acquired and parsed the 
Release file.

This would have been convenient for a quick-and-dirty mirroring approach 
where I just ask apt to fetch all the files in order to be able to reuse 
its verification logic (though I think I have another somewhat viable 
approach that will achieve many of the same goals; I'm not blocked on 
this bug report).  Recompressing/uncompressing the index files means 
that they can't reliably be served by a mirror, since their checksums 
may not match what's listed in Release.

I talked to Julian about this on Matrix, and he suggested that it 
shouldn't be too hard to allow KeepCompressedAs to take a value of 
"archive" to preserve the fetched compression format.

Thanks,
