Thanks. I looked into libblkid and it seems simple enough. I can include it as a new authentication method.
Still the systemd dependency might not be as bad as I thought initially. It turns out that the devices in by-uuid are created by udev. It is a fact that udev is part of systemd, but there are alternatives. There is Eudev, that seems to provide a similar support but is free of systemd. I was not able to test this, I do not have Gentoo. I do have FreeBSD, which does not have systemd, as far as I understand. There the component is devd and it does provide the necessary functionality. Since I had to test it in FreeBSD I added the code to repository, version 0.2.0-alpha. I also updated the README with all this information about udev/ eudev and devd.
