add-apt-repository should write to a new file in /etc/apt/sources.list.d/ rather than /etc/apt/source.list

[Adam Nelson]

Package: python-software-properties
Release: 9.10 karmic-update

Expected: When running "sudo add-apt-repository "deb http://us.archive.ubuntu.com/ubuntu/ karmic multiverse", I expected a new file to be inserted in /etc/apt/sources.list.d/ with the new repository.

What happens: Instead, /etc/apt/source.list was moved to /etc/apt/source.list.save and /etc/apt/source.list was updated.

Typically, if a debian package has configuration changes, they should be in the .d/ directory for management (i.e. if urls are changed in the base installation, etc...)

What do you think about a option for this? Like --sources-list-file ? The default for PPAs is already a sources.list.d file.

[Adam Nelson (adam-varud)]

I think we could just change the default behavior and not bother with a flag.

If anybody wants to do it the way it is now, it's easy enough to manually edit the source.list file directly.
