[Message part 1 (text/plain, inline)]

I have slow internet :)

It looks like ftp://tug.org has a FTP session timeout of 2 hours 11 minutes, or something like that.
Over night I tried to build sbcl and failed. Note how download silently stopped at ~80% [1].

Would be nice if guix had a mechanism to reconnect to FTP and continue download after timeout.

Thanks!
