Do all custom ROMs (CM or AOSP) already support dual boot in versions 4.3 or 4.4? Do they create /data/data_sec...or similar (/data_sec_rom, /system_sec_rom or whatever) during the installation?
In my case: if I copy CM 10.2 from the second rom to the first rom, will both still work? I'd like to upgrade to CM 11 in the first rom. Now that Dorimanx has proper CWMR I hope it can be done easily.
