AFAIK, it only uses sources.list, unless there is
something /etc/apt/sources.list.d, which is added first to the list it
looks of repositries it compares.

I have a collection of sources.list-YYMMDD in my /etc/apt formrecovery
and references but it existence has no effect.

IME, when you do apt/apt-get/aptitude update, it lists the sources.list
entries that it references and it should show all jessie or ascii.
