Well, the idea was to make yum not ask about confirmation when doing yum install, like: $ rpm --import https://... $ yum accept-key ... $ yum install passenger Because, when I do `yum -y install`, I don't know in advance which questions I'm answering with yes. And for the second command I was given: $ yum makecache -y --disablerepo=* --enablerepo=passenger Which doesn't convey the intention. Considering this, I'm now leaning to using `yum -y install`.
