I'm reading a few automated scripts written at work, and I'm seeing either yum clean all or yum clean metadata after creating a .repo file in /etc/yum.repos.d for a new repository. Now, I'm automating something for which I'll have to add a new repo file and I'm wondering if this does something other than cleaning the cache and if I should add it, but I don't want to add anything without really understanding what it does.
EDIT: It's suggested even here in this answer:

Recommended sure is highly recommended
as far as required no..but if you (to use rpmfusion as a example) run :
(inclusion of rpmfusion-free-release.repo)
yum install vlc
WITHOUT at least yum clean metadata it is unlikely that you will get a return.
Reason being that seeing said package in older (pre inclusion) metadata is just not possible.
