[CentOS-devel] Meaning of separate kickstart/ and os/ folders in CentOS 8 repos?

What is the significance of separate kickstart/ and os/ folders in the repos?

(If you are using kickstart does that mean you should point to
kickstart/ instead of os/ in the ks file?)

I could not find a mention of it in the release notes.

E.g. under

centos/8.0.1905/BaseOS/x86_64/

my nearest mirror has
kickstart/
os/


Cheers
