This is more of a curiosity question as I try to get a better understanding of apt and package management.
I'm seeing that in my
/etc/apt/sources.list.d/ folders I have very or sometimes identical files which have the extension of
sources.list.save, and so on.
What's the point of these duplicate or similar files?
/etc/apt/ seem to be identical but
sources.list.distUpgrade shows quantal instead of raring for most stuff (I probably first installed quantal).
On the other hand, in the case of
/etc/apt/sources.list.d/ the content of the files seems to be completely identical.
Didn't find much in Google searches. I reviewed the sources.list manpage but it didn't talk much about it.
