I use CentOS 7 server. I am not getting update so I run
yum clean all
It says I want to run rm -rf on /var/cache/yum/
Cleaning repos: base epel extras updates
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
It is safe to delete folder like that on CentOS server?
