I'm using yum as a package manager since I'm on Centos. I'm working with kernel header and devel packages, and noticed some peculiar behavior that I haven't been able to find information out via googling:
Currently I have headers and devel packages installed for the current kernel, however whenever I execute a yum command to install these locally (I have the RPM's), I get differing behavior:
(note: I'm working on automating the installation, so I'm aware that doing this on my current environment is worthless. I'm just looking for some understanding of this inconsistency)
[root@host mydir]# rpm -qa | grep kernel
kernel-headers-2.6.32-573.7.1.el6.x86_64
kernel-2.6.32-504.el6.x86_64

The two packages in question are installed (devel and headers for kernel-2.6.32-573.7.1.el6.x86_64
[root@host mydir]# ver=`uname -r`

Exits with an error, however when I try the same thing for the devel package...
