Comment # 10 on bug 1175850 from Andrei Borzenkov

Workaround is

mkdir -p /etc/systemd/system/systemd-cryptsetup@.service.d
cat > /etc/systemd/system/systemd-cryptsetup@.service.d/stop-before-udevd.conf
<< EOF
[Unit]
After=systemd-udevd.service
EOF
systemctl daemon-reload

But seriously, this is just wack-a-mole.
