Here is Clockworkmod Recovery 18.104.22.168 (Non-Touch) and 22.214.171.124 (Touch) for the Nexus 10 ! I extracted the stock recovery.img from the Nexus 10 Factory Image then ran it through clockworkmod builder.
Update: Hopefully fixed recovery.fstab mount points that were causing reboots when accessing "Mounts and Storage" options.
It can be downloaded from here:
This has not been tested yet on an actual device I need testers willing to test the recovery image and report back there findings!
It can be tested by flashing the recovery using fastboot to avoid bricking your device if it doesn't work use the fastboot boot command only flash it when it has been thoroughly tested!
fastboot boot recovery /path/to/<recovery>.img fastboot reboot
