[Caml-list] opam corrupted my sources.list.

[Hendrik Boom <hendrik@topoi.pooq.com>]

Well, technically, it was the directory /etc/apt/sources.list.d that 
got an unwanted file:

opam.list

and I'm guessing that it was opam from the name of that file.

It contained the line:

deb http://download.opensuse.org/repositories/home:/ocaml/Debian_7.0/ /

This caused havoc with my system because I am *not* running Debian or 
suse, but devuan, a Debian derivative, and I am now stuck with 
aptitude tring to install a *huge* collection of unwanted and 
inconsistent packages because the dependencies in my system are 
different from those in the openuse repository.

I am still unable to use aptitude to do routine upgrades.

Why does opam do this?  And, is it indeed opam?

Perhaps devuan needs to do something special with ocaml-related 
packages, but until I know what's happening and why it's hard to know 
where to start.
