A map of ssh public keys to install for the root user

It appears that in Debian 10 (Buster) - the use of any preseed directives to configure the network is hard coded to auto (DHCP) for single NIC hosts. Multiple NIC hosts will stop and ask the operator what NIC to use for installation.

This occurs regarldess of any preseed directives. The only apparent way to configure Debian 10 interfaces at installation are to pass the netcfg/... values on the Kernel command line.

This Param specifies that the network interface should be chosen automatically, regardless of the number of NICs in the system; with the default value set to:

• netcfg/choose_interface=auto

If you replace auto with the name of the Network Interface, then the installer will use your explicitly set NIC.

For static IP assignment or, explicit NIC selection requirements, you will have to set this Param on the Machine object, the preseed directives are ignored.

An example to explicitly set a Static IP assignment for the installer is as follows:

• netcfg/get_ipaddress=192.168.1.10 netcfg/get_netmask=255.255.255.0 netcfg/get_gateway=192.168.1.1 netcfg/get_nameservers=1.1.1.1,1.0.0.1 netcfg/choose_interface=eth0 netcfg/disable_autoconfig=true
