Well it will if the config is in /etc/network/interfaces AND that file
says 'auto eth0' on one of the lines.

That's how debian has done it for over a decade now.

I did see one laptop loose its wired network recently.  The network device
is no longer showing in lspci, which is rather odd for an internal device.
Unfortunately being a Dell it seems it has a misfeature of doing an
rfkill on the wifi if it can't check the link state on the wired network,
so wifi can't connect either.  Pretty useless laptop at this point.
