Bug#1028400: Debian-installer 11.6 not saving static network configuration after DHCP

[Fabio Maione <fmaione@gmail.com>]

Package: debian-installer
Version: 0210731+deb11u7+b1

Hello, during "Graphics install" you will reach the network configurations dialogs. After DHCP assignment, at the "hostname" dialog you can go back and choose to configure network manually.

If you set a static address, the configuration will not be saved in the '/etc/network/interfaces' file on the target system.
In other words, after setting a manual ip address during install, at reboot upon installation completion, you will not find the static address in the '/etc/network/interfaces' file on the newly installed system. It happens with debian-11.6.0-amd64-netinst.iso

Thank you
