BTW - I just got around to actually use this sequence in a slightly
different context and noticed that I missed the most important part -
exact release and version number.
Correct format to produce a list for yum:
rpm -qa --queryformat="%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n"
This allows me to upgrade our staging env to latest version, test it,
then replicate exact versions in production.
