# Red Hat Enterprise Linux 8
The current stateof RHEL 8.5 support is very alpha. It is possible to install a system and install packages provided by Red Hat.
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.

## Network Installation
(note the screenshots still show v8.5, but v8.6 was just released so we proceed with it)
The machine you want to install needs to be registered in `sysdb`, so far it works best in the `rhel8_preprod` Puppet environment:
```
FQDN=...
bob node set-attr $FQDN puppet_env=rhel8_preprod
```
Optional you can set `netboot` and RHEL 8.5 installer but that can also be selected manually in be boot menu:
Optional you can set `netboot` and RHEL 8.6 installer but that can also be selected manually in be boot menu:
```
bob node netboot $FQDN
