yum kernel/kmod update weirdness

[Ralf Corsepius]

Hi,

Does anybody have an explanation for this?


# rpm -qa 'kernel' 'kmod*'
kernel-2.6.22.1-27.fc7
kernel-2.6.21-1.3228.fc7
kmod-nvidia-100.14.11-1.2.6.21_1.3228.fc7
kmod-nvidia-100.14.11-1.2.6.22.1_27.fc7

# yum update
Installing:
 kernel                  i686       2.6.22.1-33.fc7  updates            16 M
 kmod-nvidia             i686       100.14.11-1.2.6.22.1_33.fc7  livna             2.4 M
Updating:
 kernel-headers          i386       2.6.22.1-33.fc7  updates           652 k
Removing:
 kernel                  i686       2.6.22.1-27.fc7  installed          46 M
 kmod-nvidia             i686       100.14.11-1.2.6.21_1.3228.fc7  installed         7.5
M


This would cause the system to end up with this setup:
kernel-2.6.22.1-33.fc7
kernel-2.6.21-1.3228.fc7
kmod-nvidia-100.14.11-1.2.6.22.1_33.fc7
kmod-nvidia-100.14.11-1.2.6.22.1_27.fc7

This doesn't seem right to me.

do you have the yum kmod plugin installed?

Nope, just these:

# rpm -qa 'yum*'
yum-metadata-parser-1.1.0-2.fc7
yum-utils-1.1.5-1.fc7
yum-3.2.1-1.fc7

If you install yum-kernel-module

does it start doing the right thing?

Sorry, I can't try this anymore -
Meanwhile, this machine had been
updated (by manually invoking rpm). I don't have the old FC7 kernel rpms
around to downgrade it again for testing your proposal.

I should be the 'yum-fedorakmod' plugin, if you want to use
'kmod' 
kernel modules.

  Out of curiosity, which kernel is running?  2.6.21-1.3228.fc7 or 
2.6.22.1-27.fc7?  Off the cuff, I'd guessing the former, and yum is trying 
to make sure it stays installed, but is also trying to make sure only two 
kmod-nvidia packages are installed, but the logic is telling it to keep 
the two latest installed instead of the one matching the current-running 
kernel and the latest (like it's doing with the kernel).
  Wow, did that even make sense? :-)
  Just a shot in the dark.  (And yes, I would agree that the behavior is 
non-intuitive.)

It had been 
kernel-2.6.21-1.3228.fc7.i686
+ kmod-nvidia-100.14.11-1.2.6.21_1.3228.fc7.i686

while
kernel-2.6.22.1-27.fc7.i686
+ kmod-nvidia-100.14.11-1.2.6.22.1_27.fc7.i686
already had been installed.

You are guessing
correct.

I don't know if the behavior you describe is what is
implemented into
yum, but your explaination would explain what I observed.

The problem with this behavior: Should a kernel update be malfunctioning
users end up with a non-functional graphics system should they want to
"switch back to the known-to-work kernel+kmods".

  Yeah, I wasn't saying that should be the behavior.  The ideal thing would 
be for the logic in yum for kernel packages to be extended to kmod-* 
packages.  I can only imagine that's effectively what yum-fedorakmod does.
  Not that I know.

In general the kmod system w/ or w/o any plugins does not cope well
with supporting old kernels.

This is a year old, but nothing has changed since.
