It would be really useful to have dput automatically guess the host to
upload to based on the Distribution field in the .changes file.

I just uploaded a security update to ftp-master accidentally :(

Anyway, I see newer versions have a helpful allowed_distributions
configuration value that would help me prevent this mistake which I've
copied to my squeeze machine.

Thanks,

Control: tags -1 unreproducible

From what I can tell, this behaviour has been part of ‘dput(1)’ implemented
since before the reported version.

I am closing this report as unreproducible; thank you for the original
report. If you can construct an independently-verifiable test case
(sequence of steps we can independently follow) to allow us to reproduce
the unwanted behaviour, please report a new bug.
