So the first thing you should do is contact root and explain him that
one should only use --tollef if one knows what one is doing. Doing it
by default is a very bad idea, and when packagers do that, they are
doing it wrong.

Feel free to quote the author of GNU Parallel for saying so.

While it is a valid option it should never be a default option in
/etc/parallel/config, so this is a bug in Fedora 20. May I suggest you
file a bug report for Fedora 20, so that can be fixed?

That would be fine.

They are combined (similar to /etc/bashrc). This is why what you put
in /etc/parallel/config you should be very sure is needed by everyone.

(To make it work in your case, you simply remove the line containing
/etc/parallel/config from the source.)
