normal mount points

[Graham North]

Hmmm.  My system is 4.11 so that would explain /proc.   Could /net and 
/host be related to running apache or samba?  I did not knowingly create 
these "devices"  I haven't been as vigilant as I could have been for 
security (one of my reasons for an upcoming reinstall), so there is a 
possibility of the server being hijacked...?  But I don't want to assume 
the worst on false concersns..
