[CentOS] "yum update": When is new header data downloaded? (Trying to set up custom repository...)

[James Hogarth]

Indeed in my case I usually do something akin to ....

yum --disablerepo="*" --enablerepo="myrepo" clean metadata
yum -y upgrade --disablerepo="*" --enablerepo="myrepo" mypackage

when updating custom rpms (or RPMs in a specific spacewalk channel)
across systems.
