Is it possible in linux to give a user read/write access to all files and directories like root?
EDIT I have a special case. I need to create a folder structure on which I can grand a special user full access independent of the underlying permissions. It's similar to a root user on one folder and it subfolders.
I'm not sure if this is possible and how to achieve that. I was reading on ACLs but I couldn't find a solution.
