What is that ?

StorageMgrKernel is a kernel plugin that automatically mounts/redirects any storage device on any mount points you want.

What are its advantages ?

It is configurable through a config file (an app could be made)
It is a ALL-IN-ONE Storage driver as it replaces usbmc.skprx and gamesd.skprx
It fixes many issues in previous drivers
It works well with taiHENkaku or enso
What to improve then ?

Add more exports (currently only ux0/uma0)
Include in VitaShell once exports are ready
Fix suspend/resume occuring once per hour when using SD2VITA
Find a better way to refresh taiHENkaku bootstrap.self than suspending PSVita (happens when using taiHENkaku and autoremounting ux0)
Create a user app for installation + configuration (+ real time mounting if VitaShell has not all mount points)
Create a user library
Detect a key that being pressed would load an alternative config
Add multi-configs support
Create a taihen-free version for @SKGleba and other "early boot testers"
more...
Usage:

If it exists, remove gamesd.skprx and usbmc.skprx or any other storage plugin

Copy storagemgr_config.txt to ur0:tai/.

Copy storagemgr.skprx to ur0:tai/.

If it exists, copy ux0:tai/config.txt to ur0:tai/config.txt

If it exists, remove ux0:tai/config.txt.

In ur0:tai/config.txt after *KERNEL create a new line and write: ur0:tai/storagemgr.skprx

Configure ur0:tai/storagemgr_config.txt to what you want.

Reboot PSVita.
