I have a folder, wich I used once (successfully) to have a /dev/null directory (see this question), and after trying to mount again after fusermount -u, I get permission denied. asin:
$ sudo su
# cd /home
# ls -ld user
drwxr-xr-x 23 user user 12288 jun 11 08:13 user
# cd user
# ls -ld null
ls: cannot access 'null': Permission denied
# chown user:user null
chown: cannot access 'null': Permission denied
# exit
$ ls -ld null
drwxrwxrwx 3 root root 0 jan 1 1970 null
as you can see, even though the folder is owned by root, root cant access it. also root has execute permissions on my home directory just fine
