Brltty: harmless removal?

The best solution is to remove it. But if you have another package that requires it, you can omit it from dracut.

Create a file /etc/dracut.conf.d/nobrltty.conf with the contents:

omit_dracutmodules+=" brltty "

Then run sudo dracut-rebuild

Be aware that the problem won’t be solved until the reboot after the next reboot.
