According to the Ansible team, support for listing platforms in
role `meta/main.yml` files is being removed.
Instead, they recommend using `galaxy_tags`
https://github.com/ansible/ansible/blob/stable-2.17/changelogs/CHANGELOG-v2.17.rst
"Remove the galaxy_info field platforms from the role templates"
https://github.com/ansible/ansible/issues/82453
For each version listed under `platforms.EL` - add a tag like `elN`.
Q: Why not use a delimiter between the platform and the version e.g. `el-10`?
This is not allowed by ansible-lint:
```
meta-no-tags: Tags must contain lowercase letters and digits only., invalid: 'el-10'
meta/main.yml:1
```
So we cannot use uppercase letters either.
Q: Why not use our own meta/main.yml field?
No other fields are allowed by ansible-lint:
```
syntax-check[specific]: 'myfield' is not a valid attribute for a RoleMetadata
```
Q: Why not use some other field?
There are no other applicable or suitable fields.
Q: What happens when we want to support versions like `N.M`?
Use the word "dot" instead of "." e.g. `el10dot3`.
Similarly - use "dash" instead of "-".
We do not need tags such as `fedoraall`.
The `fedora` tag implies that the role works on all supported versions of fedora.
Otherwise, use tags such as `fedora40` if the role only supports specific versions.
In addition - for roles that have different variable files for EL9, create
the corresponding EL10 files, and update the variables for EL10.
