### Custom Kernel Commandline Arguments
For custom kernel commandline arguments for the installer (e.g. to provide drivers) the sysdb attribute
`kernel_cmdline` can be used:
```
bob node set-attr lx-test-02.psi.ch kernel_cmdline=inst.dd=https://linuxsoft.cern.ch/elrepo/dud/el8/x86_64/dd-megaraid_sas-07.725.01.00-1.el8_9.elrepo.iso

There are two option in providing this driver disk to the installer:
1. Download the according `.iso` file and extract it on an USB stick labelled with `OEMDRV` and have it connected during installation.
2. Extend the kernel command line with `inst.dd=$URL_OF_ISO_FILE`, e.g. with a custom Grub config on the [boot server](https://git.psi.ch/linux-infra/network-boot).
