Hi,
In apt-file 3.0~exp4, I have added the necessary bits to enable you to
do this. I am still not entirely sure I am doing you a favour or
disfavour here by doing this.
As a final warning, if you are doing this because:
* "PDiffs are slow" / "APT is slow at handling Contents files"
- Please, retry with apt/1.2~exp with lz4 as compressor. Using
lz4 gives nothing short of a factor 6 difference in runtime.
* "I pay per MB" / "I have a data/bandwidth limit"
- If you disabled PDiffs, consider re-enabling them. For about 3MB
you can get 3 weeks of updates (via PDiffs) per suite per
architecture (based on sid amd64).
- NB: Contents-source is vastly more expensive, you may want to
disable that one (especially if you do not use it).
- If 1-2MB per week per suite per architecture is more than you are
willing to spent on Contents files then please see below.
If you are not convinced by the above (which is by all means fair and
your own choice), then you /can/ configure apt-file into doing this.
Please have a look at:
* man apt-file
* The example config in /usr/share/doc/apt-file/examples
- Let me know if they work for you or not.
With that said, I intend to keep the new default config for apt-file/3.
In particularly, because I do not want to maintain a separate apt
config tree or "undo'ing" APT config that breaks when you don't download
Packages files (e.g. "APT::Default-Release").
I can understand that this change may feel like a regression to you.
However, I hope you find the provided examples as a good starting point
for a local configuration that makes apt-file behave like you want it to.
Thanks,
~Niels
