# Installation

## Minimal HW/VM Requirements
- 4GB RAM
- 64GB Disk

## Network Installation

The machine you want to install needs to be [registered in `sysdb`](../admin-guide/deployment/sample). If you don't have the bob command installed locally you can login to __lxsup.psi.ch__ to use it. Remember that you need a valid Kerberos ticket before modifying a sysdb entry via `bob`.
More details regaring `bob` can be found [here](https://git.psi.ch/linux-infra/bob).

Optional you can set `netboot` and RHEL 9 installer but that can also be selected manually in be boot menu:

```
bob node netboot $FQDN
bob node set-attr $FQDN ipxe_installer=rhel9install
```
