Red Hat Enterprise Linux 8

The current state of RHEL 8.6 support is very alpha. It is possible to install a system and install packages provided by Red Hat. The configuration management is done with Puppet like for RHEL 7.

Testing

It looks like it works already a lot out of the box, but no guarantee can be given unless your specfic setup has been tested. The epic RHEL 8.6 Alpha Test lists the currently knowns issues. Please add your bugs there too.

Major Known Issues

using a package snapshot tag (yum_client::repo_tag in hiera) different than prod will fail horribly

Major Missing Features

default user home is local unless configured to be on AFS PSILINUX-97
security patches are automatically installed PSILINUX-98
minimal default installation, aka gem, git and postfix is not installed by default PSILINUX-100

Caveats

Workstation Installation Takes Long and Seams to Hang

On the very first puppet run the command to install the GUI packages takes up to 10 minutes and it looks like it is hanging. Usually it is after the installation of /etc/sssd/sssd.conf. Just give it a bit time.

Missing or Replaced Packages

List of packages removed in RHEL 8

RHEL 7	RHEL 8	remarks
`a2ps`	recommends to use `enscript` instead	`enscript` upstream `a2ps` upstream
`blt`	-	`blt` upstream, does not work with newer Tk version (source)
...	...	here I stopped research, please report/document further packages
`devtoolset*`	`gcc-toolset*`
`git-cvs`	-	`cvs` itself is not supported by RHEL8, but available through EPEL. Still missing is the support for `git cvsimport`.

Installing a Machine with YFS and an Old Package Snapshot Tag

After the pli-firstboot script it stopps due to errors (installed yfs kernel module version does not fit running kernel). Still it manages to install everything fine.
So please restart the machine (so it loads the right kernel) and run puppet agent again to finally start and enable the yfs-service.

"yum/dnf search" Gives Permission Denied as Normal User

It works fine beside the below error message:

Failed to store expired repos cache: [Errno 13] Permission denied: '/var/cache/dnf/x86_64/8/expired_repos.json'

which is IMHO OK to not allow a normal user to do changes there.
