comment What effect do the user and role labels have on a file in SELinux?
That gives a really good general breakdown of SELinux attributes. However, where it discusses user and role, it's only reference to a Linux user account. I still see no reference to the user and role attributes as labeled on a file having any bearing over affecting the handling of the file.

comment CentOS - semanage - Delete range of ports
@MikePurcell Yeah, it's a bit frustrating. What happens is everything specify turns into a key. Thus, resulting key for any operation must be the same key as was used for the add. Blame it on the underlying kernel API.

@Brajeshwar Then I guess they suppose that since .com is a holdover and .exe is contemporary that .exe can be legitimate. Just for grins, have you tried searching for .net?

You have 9 terabytes of data and no backup. This is where you pay for your mistakes. If anything will save you, it will be a professional data recovery service and it will cost your dearly.
