SystemRescue: Alternative mode with "rootpass=MAC_ADDRESS"

[lars18th]

Is your feature request related to a problem? Please describe.
The System Rescue CD (inside the Tools menu) has the SSH server enabled by default. However, the password is not set. To enable it you can use the rootpass boot parameter. The idea is to set this parameter optionally as the value of the mac address.

Describe the solution you'd like
The solution is very straightforward, and it's described here: #1440 . We only need to enable a secondary entry in the menu that enables the parameter.

Describe alternatives you've considered
The alternative is to use a custom.ipxe menu. However, this seems to be unnecessary as the suggestion is simple, easy to implement, and doesn't break the security because it will add a new entry, that prints the password. Therefore, it will only be enabled if the user wants it.

Additional context
I hope the developers agree with this suggestion and will implement it soon.

Hi @antonym (and other developers),

Please could you add this simple enhancement (#1440) ?
Thank you.
