Netboot Image with preconfigured/random password #303

Open max06 opened 3 days ago

max06 commented 3 days ago

Good evening folks!

I'm currently preparing a pxe environment for semi-automated provisioning of many physical and virtual machines. These machines should be ready for their nixos-anywhere deployment after boot, without human interaction.

Your current installer images with their display of the generated root-password and network config is almost ideal. (It just doesn't work in my ipxe environment due to efi/memdisk.)

Could you add that functionality to the pxe images as well?

Moving this a step further: Would it be possible to specify a fixed root password (or public key) with the command line options?

Thanks a lot!

(I could probably generate my own modified images - I'm just too lazy to add another responsibility to that project. Keeping it simple and stupid.)

Did we not already support putting password hashes in the cmdline in nixos in general?

Unsure if we also import this in the netboot image, but if we don't, we can add this. Would you than still need a random password in that case?

This sounds awesome!

No, if I can specify a hash, I'm all set.

And thanks for the quick response 🙇🏼
