Yes, I found it there (after fetching the source and grepping through that :-) I looked in /usr/share/doc/apt/examples/configure-index.gz first, but I could not find it there.

The example currently only shows how to set the first compression type. An example that also sets a second fallback would be nice. > Addition: The order is defined by insertion into the list and missing Inserted before or after current value(s)? > default methods will be added automatically at runtime, so everything That's useful to mention explicitly. > you need to do to prefer gzip over bzip2 and lzma would be: > Acquire::CompressionTypes::gz gzip; That's what I did, and it works great! I got a very notable speed improvement on my sparc box, and expect even better results for my s390 system (running in the Hercules emulator). Would the following also work to use an *un*compressed packages file: Acquire::CompressionTypes::"" ""; > NEWS entry> I thought it is more a power user option and > as it changes nothing to the default so imo not fit for an entry, > but after cleaning up the documentation on this option we will > announce it as an aside in an upcoming NEWS entry, i guess. I think it's worth mentioning, especially if you could also mention, as an example, that using gzip can improve speed on slower systems.
