root has very strong permissions in Unix, but I was wondering if it can circumvent the file permission system.
I have a directory whose owner is not root, the directory has permissions
drwxr-xr-x. I know that the root user can delete files in this folder also after doing
chmod or something similar.
Can a root user also delete these files without doing any sort of
chmod etc. (for example
rm -f). Assume files itself have all permissions. I my opinion it should not be possible. This is an important production problem.
