Does anyone know what the problem is that prevents "some" from becoming
"all"?

File-roller is a graphical application, so it's not really a replacement
for unrar anyways, even if it could handle all the same files. Is there
really no command-line alternative to our buggy unrar?

Okay, thanks for this information. It's true that we can't effectively
search for this kind of command-line use.

We had mc packaged for a few years before unrar was added, so the fact
that mc can use unrar does not mean that we must keep unrar.

My opinion is that keeping unrar packaged even though it can be
exploited by attackers who can provide a crafted RAR file does not help
Guix users.
