  Title: Preserve Running Kernel On Kernel Update by Default
   
  openSUSE Distribution: Unconfirmed
  Priority
      Requester: Desirable
   
  Requested by: Robert Davies (robopensuse)
  Partner organization: openSUSE.org
   
Description:
  My suggestion is to enable multiversion kernel & preserve running
  kernel for safer kernel updates, to reduce support problems when new
  kernels won't boot. This is now possible for 12.1 by 1 line change to
  zypp.conf.
  Since Online Update was first introduced (SuSE 7.1?) it replaced the
  running kernel by default, which can lead to problems booting. For a
  while multiversion kernel has been supported by libzypp (1 line edit in
  zypp.conf). The drawback with multiversion was manual deletion required
  of unwanted kernel packages (see
  http://lists.opensuse.org/opensuse-kernel/2011-07/msg00056.html). Now
  in Factory 12.1 M3 Michel Marek has included & announced - kernel
- package retention options (see 
http://lizards.opensuse.org/2011/07/14/improved-kernel-package-retention-in-12-1/).
- The default is sane, to preserve the Lastest & Running Kernels. So lets use
- it and make 12.1 kernel updates safer for all, and by default do the
- right thing!

  Use Case:
  End user upgrades kernel to Tumbleweed and it fails to boot.
  With kernel package retention, the running kernel was saved and
  recovery is simply a matter of choosing the "good" kernel from GRUB
  menu.
   
  Business case (Partner benefit):
  openSUSE.org: To reduce support caused by kernel upgrade "accidents".
  To encourage safer testing of Kernel Team "stable" & "HEAD" kernels.
  To correct a long standing risky choice, made for implementation
  convenience of deleting old kernel package, before the new was tested.
