Public bug reported: This is the first time I'll report a bug. Right now I'm in the classroom, and not to lose the possible error, I'll post here.
The error occurs when I create a file with the owner called 'teste' and dumb (as root) the owner to 'root' with the chown and chmod 744, like this: -rwxr--r-- root teste 355 Oct 16 14:18 ls.txt The problem (for me this is a problem, maybe not) is: if I change the user 'teste' and edit the file in Vim with ':w!', I can replace the file. -rwxr--r-- teste teste 355 Oct 16 14:25 ls.txt (the owner is 'teste' now) This is a bug?
