Samba testing on CentOS 8

[Martin Schwenke]

We've been doing our CTDB and Samba testing using autocluster, based on
the official CentOS-8.2 vagrant image.  This depends on using
bootstrap/generated-dists/centos8/bootstrap.sh from the Samba source
tree.

Until recently this has worked just fine:

+ yum -v repolist all
...
Repo-id            : PowerTools
Repo-name          : CentOS-8 - PowerTools
Repo-status        : enabled

...

Repo-status        : disabled
Repo-mirrors       : http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=Devel&infra=vag
Repo-expire        : 172,800 second(s) (last: unknown)

...
+ yum config-manager --set-enabled PowerTools -y
+ yum config-manager --set-enabled Devel -y
+ yum update -y
...

However, now:

+ yum -v repolist all
...
Repo-id            : devel
Repo-name          : CentOS Linux 8 - Devel WARNING! FOR BUILDROOT USE ONLY!

...

Repo-name          : CentOS Linux 8 - PowerTools
Repo-status        : disabled
Repo-mirrors       : http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=PowerTools&infra=vag
Repo-expire        : 172,800 second(s) (last: unknown)

Total packages: 14,251
+ yum config-manager --set-enabled PowerTools -y
Error: No matching repo to modify: PowerTools.

The whole thing falls in a heap because it appears that the Repo-id's
are case-sensitive and that "PowerTools" and "Devel" have changed to
lowercase in CentOS-8.3.

I'm still using the CentOS-8.2 Vagrant image, so I'm a little confused
about why the repos are now referring to 8.3 (not shown above for
brevity, but definitely the case).  I'd certainly like to understand
this... but I doubt that will solve the problem.  :-(

I'm wondering how we fix bootstrap/config.py to copy with this change.
Does it have to be something horrible like the following patch?

diff --git a/bootstrap/config.py b/bootstrap/config.py
index 982ebae1cd1..8383aeb392d 100644

Or is there a better way?

Thanks...

peace & happiness,
