Centos 5.x
Why could this be? After I loaded a xen kernel (by mistake), yum seemed to lose its knowledge of my CentOS version. I had that fixed by "yum install centos-release" (I had first to fix the repo addresses for this to succeed).
But after that, I noticed that yum did not remember anymore, what packages were already installed. It seems that the something happens to the rpm databases. I think this is connected to kernel upgrades - that is, every time I update the kernel, the rpm databases are spoiled... (or something).
Right now both of these commands: yum list installed rpm --query -a
...produce identical results (for practical purposes). Neither list contains for example amavisd-new, which I'm sure I have installed.
Does someone know a way to prevent the "memory loss" from happening again?

Never seen this sort of 'forgetfulness'. Could you provide a bit more detail as to which version of centos5 you're running, and the full output of 'rpm -V yum centos-release' and the outpuf of 'uname -a'

Hm, my CentOS 5 is pretty recent, I believe 5.2, but cannot find this stated... Hope this helps:
[root@mail ~]# cat /etc/issue CentOS release 5 (Final) Kernel \r on an \m

Sorry, I just found that "5.2", as is apparent from my previous email. :-)
You (and your /etc/redhat-release) say 5.2, but your kernel says 5.1 (5.2 shipped with 2.6.18-92)
Also, you seem to have made several modifications to the yum components of the centos-release package as well as other bits. What did you change? It's possible that these changes may be partly responsible for your issue.

Hm, ok.
"yum update kernel" did not see anything to update (that's just because the present problem: kernel was not listed in the rpm dbs). So I did "yum list kernel" and based on that, "yum install kernel.i686".
This time the kernel update did not erase the rpm db's (or whatever happened, on two kernel updates before this).
So it seems that my system is now cured, at least for now... Don't know why. :-)

Sounds like your RPM database was corrupted. If so, there may well be other problems lurking. I'd try:
rm /var/lib/rpm/__* rpm --rebuilddb yum update
Should not hurt, and may well help avoid other problems.

You're right, I may now have packages that yum does not "see" and thus cannot update.
I rebuilt the dbs as you suggested, but nothing seemed to change - there is nothing new for yum to update. We'll see...
