User:Vaukai/Wireless networking at first boot

Some deviations from the handbook are needed to enable wireless networking from the first reboot after installation. eiwd will be installed to act as network manager and network supplicant.

Preconditions

 * Computer needs to have a wireless device known to work
 * Known ESSID and Passphrase (psk) of the network

Device driver and firmware
While configuring the Linux kernel, the necessary device drivers need to be enabled as modules () and in case the driver needs firmware the package should be installed.

Network manager
While configuring the system, from the section Host and domain information only the first step (setting the hostname hostname="tux" ) should be applied. The sections Configuring the network and Automatically start networking at boot will be skipped and the upcoming eiwd will be installed instead of netifrc.

To avoid netifrc to get pulled in, the USE flag needs to be disabled:

On next recompilation of openrc then netifrc should disappear:

Since eiwd at the time of writing is available only in the guru ebuild repository this repository needs to be added.

After syncing with guru the package can be installed:

For authentication with the network, a configuration file named after the ESSID is needed to hold the passphrase (psk).

The filename must be identical with the network name and the suffix with the network type. Passphrase= is the same as psk= known from wpa_supplicant but without quotation.

Finally eiwd will be added to the default runlevel:

Continue from the Handbook
The installation according to the handbook should continue starting from The hosts file.

Troubleshooting

 * eiwd crashes when rfkill is touched but it can be restarted . The bug is located upstream in src/wiphy.c.
