Do we need to create the persistent home directory first? Then install klik after the reboot? Do we need to use persistent home and save my config?
Yes. I found it best to save the configuration file - reboot with myconf=scan - create a persistent home - reboot with home = scan and myconf = scan

I created a 230MB PH on a pen drive. Once you start using Klik you'll find the space runs out quite quickly so a larger PH on your hard drive may be a better way to go
