+IMPORTANT! MAKE SURE TO READ THE FOLLOWING!
+
+Please remember to reinstall this port after kernel source update.  Using AoE 
+devices on boot is a little tricky because the network must be up before the 
+system can access an AoE device. The current rc boot method for automounting 
+filesystems will not work with AoE devices; vinum and mount -a are both run 
+before bringing up the network.
+
+In order to use AoE devices on boot a few rc.conf variables have been defined 
+that permit the boot script (/etc/rc.d/aoe) to initialize systems using AoE 
+devices after the network is up. They are as follows:
+
+   aoe_enable    Set to "Yes" to enable the aoe startup script. 
+   aoe_iflist    A space separated string of interfaces valid for AoE.
+   aoe_wc        Set to "1" to enable write cache on AoE device. 
+   aoe_mounts    A space seperated string of AoE device nodes to be mounted.
+                 (An entry for each needs to be in /etc/fstab as well with the
+                  "noauto" option.)
+
+For example, the following added to /etc/rc.conf:
+
+   aoe_enable="Yes"
+   aoe_iflist="em0 em1"
+   aoe_wc="1"
+   aoe_mounts="/dev/aoed0s1a /dev/aoed1s1a"
+
+and the following added to /etc/fstab:
+
+  # Device                Mountpoint      FStype  Options         Dump    Pass#
+  /dev/aoed0s1a           /mnt/a          ufs     rw,noauto       0       0
+  /dev/aoed1s1a           /mnt/b          ufs     rw,noauto       0       0
+
+will automatically start the AoE driver and mount the /mnt/a and /mnt/b 
+"blades".  See aoe(4) and http://www.coraid.com/support/freebsd/usingaoe.html 
+for more information.
