[Bug 1398148] Re: Make network/disk boot toggle preseedable in d-i

[Adam Conrad]

My point was that the late_command can run in the target, where the
tools are available and installed, there's no reason to have the tools
also in the installer environment to make this workaround go.

Title:
  Make network/disk boot toggle preseedable in d-i

Status in debian-installer package in Ubuntu:
  New

Bug description:
  ---Problem Description---
  The Ubuntu installer alters the boot order for PowerVM LPARs, which affects automated testing (using network installation). e.g, if the original boot order is network then disk in SMS, after 14.10 installation, the boot order is disk. That means automatic installation will fail, as the network won't be used to boot at all.

  I already work around this on other distributions that have made the
  same decision by restoring the original boot order, but it seems that
  the Ubuntu installer's limited environment contains none of the
  necessary tools (nvram, nvsetenv or bootlist), so it's not possible
  currently.

  This is mostly an request for information to Canonical on:

  1) if this was intentional
  2) if it's possible via preseed to not rewrite the boot order
  3) if some or all of the above mentioned tools can be present in the installer
    
   
  ---uname output---
  Linux ltcbrazos2-lp03 3.16.0-23-generic #31-Ubuntu SMP Tue Oct 21 17:55:08 UTC 2014 ppc64le GNU/Linux
   
  Machine Type = IBM,9119-MME 
   
   
  ---Steps to Reproduce---
   Attempt to install over the network via boot order in SMS. After successful installation, on the disk is in the boot order.

  Drop to a shell in the installer and attempt to run any of the commands.
   
  Install method: Cobbler (DHCP/HTTP)
   
  Install disk info: N/A
   
  Install ISO Information: 14.10 from cdimage
