[Bug 1579391] Re: extlinux broken in ubuntu

[Tong Sun]

** Description changed:

  The extlinux under Ubuntu has been broken since Vivid, and it is still
  not fixed in Ubuntu 16.04 LTS Xenial.
  
  What I got:
  
  In Vivid, having installed extlinux, I still don't have the
  extlinux.conf configuration file, so I do it manually again:
  
  % extlinux --install /boot/extlinux
  /boot/extlinux is device /dev/sda7
  
  % dir -l /boot/extlinux
  total 116
  -r--r--r-- 1 root root 116632 May  1 21:21 ldlinux.c32
  
  What is expected:
  
- According to the official doc at http://www.syslinux.org/wiki/index.php/EXTLINUX, 
+ According to the official doc at http://www.syslinux.org/wiki/index.php/EXTLINUX,
  "extlinux --update /boot/extlinux" will
  generate extlinux.conf under /boot/extlinux, and it has always been working like that before, until I'm testing it under Vivid.
  
  In Xenial, things are still the same:
  
  % apt-get install extlinux syslinux-common
  Get:1 http://archive.ubuntu.com/ubuntu xenial/universe amd64 extlinux amd64 3:6.03+dfsg-11ubuntu1 [130 kB]

  -rw-r--r-- 1 root root 37950863 May  7 14:58 /boot/initrd.img-4.4.0-21-generic
  
  I had been able to workaround the problem by installing the working
- extlinux packages from prior to Vivid, but not any more under Xenial, in
- which I will get:
+ extlinux packages from Ubuntu in Vivid,
  
- % extlinux --install /boot/extlinux
- extlinux: cannot find device for path /boot/extlinux
- extlinux: cannot open device (null)
- 
- I.e., using the previous working extlinux packages no longer works under
- Xenial. The system cannot boot any more.
+ But since the extlinux package is reintroduced in Xenial again, I kept
+ getting prompted to upgrade it,   thus it is more of a issue now.
