[Bug 1604891] Re: The kernel version is different between mini.iso and ubuntu 14.04.3 LE

[Adam Conrad]

mini.iso is meant to be a self-contained booting ISO, just as the full
server ISO is.  You can use the initrd/kernel from either *together*,
but you can't mix and match both.

If you want the initrd from mini.iso for some reason, then why not use
the kernel from there too?  They will always match.

The netboot.tar.gz that Steve mentions is the one linked from
http://cdimage.ubuntu.com/netboot/xenial/ and sitting right next to the
mini.iso

Specifically: http://ports.ubuntu.com/ubuntu-ports/dists/trusty-
updates/main/installer-ppc64el/current/images/vivid-
netboot/netboot.tar.gz

Also of note, the utopic/vivid/wily images are out of support.  The only
kernels we support on trusty are trusty (3.13) and xenial (4.4).

Title:
  The kernel version is different between mini.iso and ubuntu 14.04.3 LE

Status in debian-installer package in Ubuntu:
  Invalid

Bug description:
  ---Problem Description---
  mini.iso for ubuntu 14.04.3 LE is not available 
   
  Contact Information = gfgaogf at cn.ibm.com 
   
  ---uname output---
  ~ # uname -a Linux (none) 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:17:43 UTC 2015 ppc64le GNU/Linux
   
  Machine Type = S822LC(openpower-firestone) 
   
  ---Debugger---
  A debugger is not configured
   
  ---Steps to Reproduce---
      We want to boot from network using Ubuntu14.04.3. So we use initrd.gz from mini.iso, and vmlinux from Ubuntu 14.04.3 full LE ISO.  We use the two files as booting files.

  We download ISO from
  http://cdimage.ubuntu.com/releases/14.04.3/release/ubuntu-14.04.3
  -server-ppc64el.iso

  We download mini.iso from http://ports.ubuntu.com/ubuntu-ports/dists
  /trusty-updates/main/installer-ppc64el/current/images/vivid-
  netboot/mini.iso

  The kernel version of mini.iso is "3.19.0-32". But the kernel version
  of 14.04.3 full le ISO is "3.19.0-25".

  My questions:
  Can we use them by the mixed method? The mini.iso and the le full iso should not have the same kernel version?
  Or if the mixed method is not permitted, if I want to netboot ubuntu14.04.3, where can I get the mini.iso or the netbootable initrd.gz?
