Thanks! I agree with your reading that changing the default username and password and re-exporting would count as modification.

However, it seems there are plenty of Ubuntu .deb mirrors out there... and there are even instructions at https://help.ubuntu.com/community/Debmirror.

Your previous post said "you can't redistribute Ubuntu binaries or sources as-is, since they contain registered trademarks of Canonical" (emphasis mine), which I think isn't quite true - there has to be some modification involved to fall foul of Ubuntu's IPR.

Oops, you're right, I misspoke - I was thinking about the modification step as a given, but that's not what I said. Apologies for the confusion.
