Description Dave Jones 2007-04-13 15:08:54 UTC

10:43 < davej> skvidal: re the magic in yum that makes sure the current running
kernel isn't removed during an upgrade..
10:43 < davej> can you add 'kernel-debug' to that list?
10:43 < skvidal> ah, probably
10:43 < skvidal> you should stop making up all these new kernel names :)
10:43 < davej> I just found out the hard way that that's a good idea ;)
10:43 < davej> I think I'm done for a while :)
10:44 < skvidal> hmm
10:44 < davej> the RHEL people did kernel-rt recently too, which should probably
be on the list
10:44 < skvidal> kernel-debug is listed
10:44 < skvidal> what ver of yum do you have?
10:44 < davej> ooh. spooky.
10:44 < davej> 3.0.6-1.fc6
10:44 < skvidal> one sec
10:45 < skvidal> hmm, it's on the installonlypkgs for that ver, too
10:45 < skvidal> so when did it get removed
10:45 < skvidal> ?
10:45 < davej> yesterday
10:45 < skvidal> you don't have anything special in your /etc/yum.conf, do you?
10:45 < skvidal> and what was the operation it was doing?
10:46 < davej> stock config.
10:46 < davej> yum -y update
10:46 < skvidal> can you send me your /var/log/yum.log?
10:46 < skvidal> or at least the last couple of days?
10:48 < davej> http://www.codemonkey.org.uk/junk/yum.log
10:49 < skvidal> this is a stock yum config for fc6?
10:50 < davej> yeah, should be
10:50 < skvidal> which kernel-debug pkg got removed?
10:50 < davej> looks like it
10:50 < davej> 2.6.20-1.2933.fc6 I think
10:51 < davej> I only have 2943 and 2944 installed now
10:52 < skvidal> okay - this seems like installonlyn took it out
10:52 < skvidal> but 2.6.20-1.2933.fc6 was running?
10:52 < davej> yeah
10:53 < skvidal> then it might be that installonlyn is doing something
not-quite-right when it comes to handling kernel-debug kernels and checking for
them being the running 
                 kernel
10:54 < davej> *nod*
10:54 < skvidal> I'll see what I can come up with
10:54 < skvidal> but could you file a bug on this against yum

The recent yum update (yum-3.2.2-1.fc7) may introduce more problems like this:

from man yum.conf:

| installonlypkgs
|              List of packages that should only ever be installed, never
|              updated. Kernels in particular fall into this category. 
|              Defaults to ‘kernel, 
|              kernel-smp, kernel-bigmem, kernel-enterprise, kernel-debug,
|              kernel-unsupported’. 

Imho kernel-PAE and kernel-xen are here missing, also the installonlyn 
supported some more kernel packages, here are the suffixes:

 31     for s in ("bigmem", "enterprise", "smp", "hugemem", "PAE", "rt",
 32               "guest", "hypervisor", "xen0", "xenU", "xen", "debug"):

And will the new yum also keep the the regarding -devel packages installed?

Oh, when I look into the source 
(/usr/lib/python2.5/site-packages/yum/config.py) the default values differ in 
reality:

490     installonlypkgs = ListOption(['kernel', 'kernel-bigmem',
491             'kernel-enterprise','kernel-smp', 'kernel-modules', 'kernel-debug',
492             'kernel-unsupported', 'kernel-source', 'kernel-devel'])
493     installonly_limit = IntOption(2)
494     kernelpkgnames = 
ListOption(['kernel','kernel-smp', 'kernel-enterprise',
495             'kernel-bigmem', 'kernel-BOOT'])
496     exactarchlist = ListOption(['kernel', 'kernel-smp', 'glibc',
497             'kernel-hugemem', 'kernel-enterprise', 'kernel-bigmem',
498             'kernel-devel'])

Is it correct that kernelpkgnames and exactarchlist do not include every 
kernel package name that installonlypkgs does?

Comment 2 Seth Vidal 2007-12-07 02:45:25 UTC

Is this still happening? It seems to have vanished in one of the various updates.
reopen if it is, okay?
