Run an FRP client during system boot using Dracut.

Meant for use with dracut-crypt-ssh to remotely decrypt a Fedora server that is behind NAT.

Also supports secureblue.

1. Prerequisites:
   • Ensure a network connection is available in the pre-boot environment.
     • For a wired connection on systems that use GRUB, this is as simple as adding rd.neednet=1 ip=dhcp to the GRUB_CMDLINE_LINUX variable in /etc/default/grub, then running grub2-mkconfig --output /etc/grub2.cfg.
   • Ensure whatever services you'll use FRP for (for example, an SSH service via dracut-crypt-ssh), are also already setup to run in the initramfs environment.
2. Run setup.sh. This will:
   1. Download the latest version of FRPC.
   2. Grab a user-defined FRPC config file.
   3. Install the Dracut module.
