Unable to start Bind on a fresh RHEL 8.6 system with enforcing SELinux

[Michał Kępień]

Søren,

> On a fresh install the selinux context are 'var_t', and if I changed it to 'named_var_run_t' it works!

This is the suspicious part for me.  How did you install the packages?
The only supported way is the one that is documented [1]:

    dnf install isc-bind

That pulls in the SCL metapackage which sets up SELinux file context
equivalency rules [2] and relieves you from having to apply any sort of
manual SELinux context tweaks.

My guess is that you installed one of the "individual" packages
directly, e.g. "dnf install isc-bind-bind".  Please be aware that if the
SELinux contexts are not set up by the metapackage, you may run into
other similar issues in the future.
