At the moment I have to ask our customers for installing updates and then start the yum update progress. Now the customer have to wait while yum downloading all the packages and then installing it.
It will be much useful if I could first downloading all packages and with yum update only installing them.
Thanks in advantage
You can run:
yum install yum-downloadonly
yum update -y --downloadonly
...and then run:
yum -C update -y
...note that you must use "-C" to run from cache, this should be fine as you've downloaded everything.
