It's unclear to me where you got that from. In all Linux man pages I looked up 
so far it said S_IFSOCK was supported. But I also tested this now with 
security_model=none on a Linux host and it works as expected, i.e. it creates 
a file of type socket on the Linux host filesystem.

We are really talking about a Linux host, right?

Best regards,
