This is mainly for EPEL10 planning, but others might find it useful, so I'm
sending it to the email vs the epel10 discussion on discourse.
I was talking with Carl about creating a dnf variable for the epel 10
repos. He had been talking about using $releasever and $releaseminor. But
we also talked about creating our own epel variable.
This is about creating our own epel variable. I'm calling it epelrelease
but that it up for debate.
There is an often overlooked file called /etc/os-release
It's full of lots of good stuff, including a variable called "VERSION_ID"
In every Red Hat compatible release (Fedora, Stream, RHEL, Alma, Rocky)
this should give us what we need/want.
Fedora 39
Stream 8 / 9
RHEL 8.7 / 9.1
Alma 8.7 / 9.1
Rocky 8.7 / 9.1
The format of /etc/os-release makes it very easy to use. The following
would give us a dnf variable called epelrelease
source /etc/os-release ; echo $VERSION_ID >> /etc/dnf/vars/epelrelease
We could then use epelrelease in our dnf configs.
How to set it, I suggest triggers. But that needs a bit more investigation
and testing.
