Yes, but you can't switch existing package feeds from one setting to
another with deb, because of file conflicts (unless you run apt-get -f
install after upgrading). This would need additional RREPLACES,
RCONFLICTS (and RBREAKS?) statements, which IMHO are impossible to
automate. I'm not sure about other package managers. But it's a very
common problem when moving files from one package to another.
