I investigated this further. The problem is that while building the
Dracut image, it's looking for keytab and other data files under
/etc/brltty, whereas in the Arch Linux package, they're located under
/usr/share/brltty. The directory is hard-coded in the shell script.
Here are the error messages for reference.
