Wait a second, are you really suggesting that OE-core should have a
default root password in its default configuration?

That's very bad practice and I'm against doing it this way. Having a
default password is one of the common vulnerabilities in actual devices
on the market today. OE-core should make it hard to make that mistake,
not actively introduce it.

So if you think that having a root password set (instead of empty), then
at least make it an opt-in behavior that explicitly has to be selected.
Make it an image feature so that images with and without default
password can be build in the same build configuration. Changing
base-passwd doesn't achieve that.

Even then I'm still wondering what the benefit of a well-known password
compared to no password is. Both are equally insecure, so someone who
wants to allow logins might as well go with "empty password".
