New issue by thomas-t-w on void-packages repository

https://github.com/void-linux/void-packages/issues/12173
Description: I don't know how this should be implemented into a build script and which program we should use to get the random text. I guess it goes into post_install()? If someone tells me which program would  be best to use to generate the random string, I will try to implement it.
### System

* xuname:  
  *output of ``xuname`` (part of xtools)*
* package: brltty6.0_1
  *affected package(s) including the version*

### Expected behavior
If the file is created, programs like orca screen reader can use the brltty api to display text on a braille display. https://en.wikipedia.org/wiki/Refreshable_braille_display
### Actual behavior
I had to create this file manually and add text to it.
### Steps to reproduce the behavior
Install brltty package.
