If you're so inclined, log in to the pi and run:
pwd
ls -al
then run sudo -i and:
cd /root
ls -al
cd /
ls -al
and post the results of the pwd command and all the directory listings (the ls -al commands). Those commands will show the contents of the SD card as seen by linux running on the pi:
- The directory you log into
- The contents of that directory with all the permissions assigned to each file and subdirectory
- The contents of the /root directory with all their permissions
- The contents of the / directory with all their permissions.
Of course, and thanks for sticking with me here..
Here is what I get:
