== Manager payload behaviour ==
* Manager/sprx contain lv2ldr keys inside
* dev_blind is unmounted
* dev_wflash is mounted writeable
* Manager contains unself/createself for patching ps2 emu files (to patch a crypto stub and add *install packages* to "/dev_wflash/vsh/resource/explore/xmb/category_game_tool2.xml"), while the message "Installing PS2 support. Please wait..." is displayed

note: mounting dev_flash writeable is also seen with reDRM dongles.
