[Spacewalk-list] question about updates not found by yum but by up2date

[Michiel van Es]

Hi,

I got some machines (centos 4 clients) who are showing updates in
spacewalk but when I click on them I don't see any of them.
I know this is a known bug but what I find strange is that when I do a
yum update on the machine (spacewalk client) it finds no updates.
When I do an up2date -fu it installs updates:

[root at supwf01p ~]# yum update

Why doesn't yum find any updates and up2date does?
I thought both use the same spacewalk repositories?

Kind regards,

Michiel
