 '''<kernel_name>''' is the name of what you selected in the initramfs creator, and the name of the outputted file.
 Once you do this just go to your bootloader config, and add it in there.
 Example:
   kernel name is: bzImage-3.7.1-ALL
   initramfs name is: initrd-3.7.1-ALL.img
-  pool name is: rpool
+  pool root is: rpool/ROOT/funtoo
   encrypted root is: /dev/sda2

 == Getting back into your ZFS pool in case of emergency ==
 If you ever need to get back into your ZFS pool in case of an emergency (missing rebuild of modules, unable to boot, etc) reboot your box with the System Rescue USB you created earlier, then issue the following commands:

 == Extra: After reboot ==
 After you restart your machine and your inside your desktop, continue to set up anything you need in terms of /etc configurations. Once you have everything the way you like it, take a snapshot of your system. You will be using this snapshot to revert back to this state if anything ever happens to your system down the road. The snapshots are cheap, and almost instant. To take the snapshot of your rootfs, type the following:
 <console>
 # ##i##zfs snapshot rpool/ROOT/funtoo@install
 </console>
 To see if your snapshot was taken, type:
 <console>
 # ##i##zfs list -t snapshot
 </console>
 If your machine ever fails and you need to get back to this state, just type:
 <console>
 # ##i##zfs rollback rpool/ROOT/funtoo@install
 </console>
