While configuring unattended-upgrades, I noticed that repositories at Debian follow a very inconsistant scheme:

"origin=Debian,codename=${distro_codename}-security",label="Debian-Security";
"origin=Debian,codename=${distro_codename}-updates",label="Debian";
"origin=Debian,codename=${distro_codename}",label="Debian";
"origin=Debian,codename=${distro_codename}-backports",label="Debian Backports";
"origin=Debian,codename=${distro_codename}-debug",label="Debian debug";

Some are hyphanated, others capitalized, others not capitalized, etc.

It would be desirable to have a policy item for naming these and for the Debian repositories to follow it.

Thanks!
