|
## Hardware Compatibility

- [Hardware Compatibility](hardware_compatibility.md)
|
|
|
|
## Alpha Testing
|
|
|
|
We encourage you to install RHEL9 on testing systems and tell us what we may have broken, what bugs you run into and what features you are missing. Please be aware of certain things we changed on how we want the base operating system to work, listed below.
|
|
|
|
Bugs and issues can be reported in the [Linux Issues project](https://git.psi.ch/linux-infra/issues).

|
## Changes for Base Installation
|
|
|
|
### No Support for AFS
|
|
The future support model for AFS or the service and functionality it provides is currently under consideration. Consequently it has been decided not to support AFS in the PSI RHEL9 distribution at the time being.
|
|
|
|
|
|
### Network Configuration
|
|
By default the network configuration is handed over to NetworkManager which does automatic configuation.
|
|
|
|
If you wish different behaviour, e.g. for static IP addresses, please check out the [Network Configuration guide](../../configuration/basic/networking.md).
|
|
|
|
|
|
### Disk Layout
|
|
Provided disk size is 64GB for virtual machines.
