I rarely use CD/DVD for installs, esp ks installs, so add salt.

I think the CD is directly accessible if your %post is not chroot. Have 
a look at vc1 during any install to see what's there.

I think the CD is not directly accessible if your %post is chroot. It's 
possible to mount it, but doing so requires some effort, or basic 
assumptions relying on the way you work. Simplest, is to copy from a 
non-chroot %post and use from a chroot %post. It's legitimate to have 
more than one (and for them to be in different languages).
