Comment 39 for bug 658865

Removing the apt-setup/generators/40cdrom file requires that one have net connectivity to complete the installation.

What's the point of having a cdrom, or usb stick with a complete distro except to either avoid the overhead of (repeated) download(s) (multiple installs) or a slow net connection to begin with (some of my friends still use dialup).

My problem is potentially compounded by the fact that I'm installing UEFI.

I don't like either of these workarounds, there must be something better.

What's the purpose of the cdrom-detect/try-usb=true boot arg?
Isn't that supposed to offer a clue that /cdrom is really a USB?
TIA
