Overview

x200-my is a simple openrc script primarily designed to make the distinctive whining noise of Thinkpads X200 disappear. But it can also be used on other laptops.

It is written to be used on Hyperbola GNU/Linux-libre but it should work on other Arch-based + openrc distributions.

Privacy Settings

It also provides a “Privacy settings” section: if enable_privacy is set to true, then the wired internet interface that may or may not be connected to the internet will have its MAC address spoofed at startup. (The wireless interfaces must also be spoofed, but this can be handled by wpa_supplicant: see below.) Additionally, x200-my will delete /etc/dhcpcd.duid, which will make dhcpcd generate a new DUID-LLT based file with an updated timestamp and the spoofed link-layer address of the network interface that is connected to the DHCP device at the time that the DUID is generated.

Backup

Finally x200-my has the ability to backup essential files or directories—for instance to a backup disk mounted inside the dock. Of course, the backup process is triggered on certain conditions only:

  1. The option must be enabled in the /etc/conf.d/x200-my file.
  2. The disk must be mounted.
  3. An (empty) dobackup file must be present in the backup directory.

Then, once these conditions are met, the backup process is triggered whenever the service is stopped. It additionally generates a list of installed packages in case the disk should die and everything should be reinstalled.

Installation

  1. Clone this repository locally.
  2. Do makepkg.
  3. Install the generated x200-my package as root with pacman -U.
  4. Edit /etc/conf.d/x200-my.

It is advisable to use x200-my in conjunction with wpa_supplicant and dhcpcd only. In addition, wpa_gui and dhcpcd-ui are also recommended.

For this to work properly, it is important to have these two lines in /etc/wpa_supplicant/wpa_supplicant.conf:

mac_addr=1
preassoc_mac_addr=1

And these settings in /etc/dhcpcd.conf:

hostname "localhost"
hostname_short
