title: Unable to install kernel driver rpm during %post section kickstart RHEL7
body: <p>I'm trying to install a custom driver rpm that I custom built. I have a kickstart file bundled into a RHEL7.2 iso with a <code>%post</code> section. In the <code>%post</code>, I have a yum install of the driver rpm which seems to get installed, but I notice that depmod logs fatal errors when the driver rpm gets installed:</p>
  
  <blockquote>
  <pre><code>Installing : kmod-xnxx-1.0-1_test.x86_64
  depmod: FATAL: could not load 3.10.0-327.el7.x86_64: No such file or directory

  <p>As the rpm gets installed, it runs a depmod -a and dracut to rebuild the ramdisk. I'm not sure why these errors a re occurring during the anaconda post install? I've confirmed that the same kernel "3.10.0-327.el7.x86_64" is being used during the post so I have no idea why the module doesn't get installed correctly without the "depmod" errors. I recall from the past that the running kernel during the anaconda install has differences with the kernel that actually gets installed. I'm not sure if this is attributed to the issue I'm having with the post. Any suggestions on how to overcome this would be great. Thanks!</p>
  
  <p>Below is the spec file that I'm using to build the kernel driver rpm(kmod) against kernel 3.10.0-327.el7.x86_64:</p>

  %define current_kernel %(uname -r)
  
  %define destdir /lib/modules/3.10.0-327.el7.x86_64/kernel/drivers/net/
