I use PXE debian installer and install it from the local network mirror.
It only offers to install "squeeze - stable" despite of there are both squeeze and lenny on the mirror.
How to force it to install oldstable (lenny)?
When I use legacy network-boot installer, it offers both "oldstable - lenny" and "stable - squeeze", but when I use new one it only offers "stable - squeeze". Can the new installer install old Debian?
