/apex isn't mounted

[bjacob]

I'm trying adeb on a Pixel4, Android 10. There's a root directory named /apex. It's not mounted. Indeed this code isn't mounting it: https://github.com/joelagnel/adeb/blob/master/addons/run.common . I made a naive attempt at copying what's done for the other directories with mount --bind. That gave me a /apex with the right sub-directories inside it, but these subdirectories were all empty.

This is a dupe of #38 .
