Hacking Ux0 without memory card?

[Unessential]

I bought a PSTV and installed henkaku

I don't have a memory card (I even double checked the slot just now)

I read all the descriptions of the drive assignments, and went into the molecule shell and...

....I have a ux0...?

I thought ux0 was supposed to be the memory card slot. and ur0 internal storage.
What is my ux0 right now with no memory card inserted? I've been installing all homebrew and hacks on it...

What will happen with the data/how will the pstv react if I insert a memory card?
Will the 'current' ux0 get reassigned to something else? Is ux0 actually a mix of some internal storage and a memory card?
Will a memory card simply replace the data and I will no longer have access to it?

And even weirder what if i use things like vita2SD? or USB (normally assigned to uma0) But assuming inserting a memory card will "merge" them somehow
will these things have wierd interactions as well?

The PSTV and Vita Slim have 1GB of internal storage as ux0. When you insert a memory card, the system uses that as ux0 instead. Same with SD2Vita and USBMC if mounted to ux0.
