Dear Guido Martínez,

Are all Debian .deb packages compressed with the xz compression? How
many packages would benefit for this being supported at the package
infra level vs. handling it directly in the toolchain-external package?
We normally try to not clutter the package infra with features only
useful to one package, especially when the feature can easily be
implemented at the package level.
Best regards,
Thomas

I had tried with several packages and found they were all XZ-compressed, but I just tried with ~6000 packages and saw that only 90% are XZ-compressed, so this wouldn't work. I also don't know of any packages we might want to use are only shipped the .deb format. > We normally try to not clutter the package infra with features only > useful to one package, especially when the feature can easily be > implemented at the package level. Yeah, I agree. I'll drop this and revert back to custom extract commands.
