How to set up a bridge without additional packages in debian?

Question

linux

In general, according to the topic, for example, there are 2 interfaces eth0 and eth1, everywhere they write that you need to install bridge-utils, but I don’t understand why, if the interfaces file is still edited by hand!?
those. simple

auto br0 
iface br0 inet dhcp
 bridge-ports eth0 eth1

won't it be enough?
or is this package needed for bridge-ports and other things?

Answer 1

Try not to install bridge-utils and find out.
Scripts that read /etc/network/interfaces are just a wrapper around some system packages. No package - the script will not be able to configure the interface
