Title: Keep the current kernel when doing a kernel update through yast

openSUSE-11.4: Unconfirmed
Priority
Requester: Desirable

Requested by: Wilfred van Velzen (wvv)
Partner organization: openSUSE.org

Description:
See this discussion on the forum:

http://forums.opensuse.org/english/get-help-here/install-boot-login/447030-keeping-current-kernel-when-doing-kernel-update-through-yast.html
 
Summary:
Keeping the current kernel installed should be the default and
automatic behaviour for a kernel update through Yast! (Provided there
is enough space on the partition that holds /boot).
Or it could be a setting somewhere to keep the last X number of
previous installed kernels (where X should default to 1).
 

Business case (Partner benefit):
openSUSE.org: When the newly installed kernel doesn't work or has some
issues. The user has an easy way to boot into a previous kernel, so he
still has a working system.

I also agree that by default, openSUSE should maintain both old and new
kernel versions so that in the event of a bad or defective kernel
installation, it would be easy to drop back to an older kernel
version.  I would add this as the default method in openSUSE 11.4 to
allow the addition or removal of kernel versions, but that loading a
new kernel does not automatically remove the older version.
 
Thank You,
J. McDaniel

The advantages of always having a useable kernel far outway any savings
made by not keeping the old  kernel, and those savings are what? a few
meg of disk space!

the one i like about opensuse is not to have billions of kernels when i
start up like ubuntu and debian does. it should be optin. i dont realy
like it to uninstall old kernel by hand, espacialy not if you have to
do that on several machines.

Hi,
 
Mandriva does it since 2009.1 I think and there is no need to erase old
kernels, it is done automatically. I d'on't know how they do it though.
When there is an upgrade of kernel k, the system keeps the k and k-1
and thus erasing the k-2 and + kernels and entries in GRUB.

we had at least 2 major kernel update errors in the last years, so this
option is really necessary. May be simply make the menu name softer
(now it's the full kernel name), could be "openSUSE", 3failsafe...",
"openSUSE old Kernel Failsafe" (full one kept but commented out)

#6: Martin Seidler (pistazienfresser) (2010-10-05 14:40:12)
By the way:
Maybe there could be also added an easier way to test a kernel before
it is in the main repositories. An easy fallback to the kernel from the
main repository (update or 11.x) may be an stimulatition for not so
willing to take risks (or at least something to minimize the
determent).  And hopefully the more a kernel is tested on diffenrent
system the more it will likely be stable if it is intruduced to the
main update repository.

This thread demonstrates a production system that could have benefited
from multiple installed kernels.

+ I agree with the suggestion in the summary and made somewhat the same
+ suggestion to #306971. I currently use multiversioning but have to keep
+ track of how many generations I have and remove older ones.
+ Thank you,
