Is Android System [UID] in your list of SU Root Permissions?

I just reloaded the stock rom then installed SuperSU (otherwise blank system) 

Upon the next restart, one of the permission request that popped up is Android System [UID]. : system\_user\_1000

I don't remember seeing this before...

This is normal? Could this be malware?
