Josué, any thoughts?
1) As someone pointed out in the thread, the reason why isc-dhcp-client had priority:important probably was to ensure that debootstrap would pull it, since debootstrap ignores Recommends and packages with a priority lower than standard. 2) However, as long as ifupdown explictly depends on a package, it can also pull dependencies with a lower priority. Right now ifupdown Recommends "isc-dhcp-client | dhcp-client" which debootstrap would ignore. It would have to Depends "dhcpcd-base | dhcp-client" instead. 3) At that point, swapping the priority of isc-dhcp-client and dhcpcd-base merely becomes "nice to have". Heck, the priority of both could, in principle, be optional, just as long as ifupdown explicitly Depends on a DHCP client, and the first alternative is a real package. Martin-Éric
