listdir() & listdir("./") do not work the same. Mounts are ignored.

# mount a vfs under /something
import os
os.listdir()
os.listdir("./")

Behavior

>>> listdir()
['ramdisk', 'LjinuxRoot', 'code.py', 'lib', 'boot_out.txt', 'ftp_serv.py', 'boot.py', 'repl.py', 'settings.toml']
>>> listdir("./")
['LjinuxRoot', 'code.py', 'lib', 'boot_out.txt', 'ftp_serv.py', 'boot.py', 'repl.py', 'settings.toml']
>>> 

Description

I just started playing with ramdisk more, and I noticed my ls was just.. not seeing it..

I believe I ran into a similar issue with SD card mounts.

[RetiredWizard]

When the os.listdir('..') is run from a mounted directory (SD card anyway) the mounted folder is listed rather than the root folder. I.E. the ".." directory shortcut can't parse up thorough a mount point.

The os.chdir('..') command has the same issue.
