[Differential] D10603: distinguish NFS versus TFTP boot by rootpath

[bapt (Baptiste Daroussin)]

bapt added a comment.


  What I mean is we cannot use the one I listed above because they are interpreted by ipxe. For example if one netboots from qemu it will use ipxe under the hood first, then if you pass rootpath tftp:/ ipxe will say
  
    Next server: 192.168.42.1
    Filename: /pxeboot
    Root path: tftp:/
    Could not open SAN device: Invalid argument (http://ipxe.org/1c126002)
    No more network devices
  
  and the boot process fails.
  
  Which is why what I propose is tftpfs:/ because it is not used by ipxe
  and by default we remain on over nfs so we don't break existing usage
