However, to abstract from your RedHat-centric view and old-fashioned alias specifications, I'll try to answer more fully. While Linux does allow multiple addresses to be associated with one interface (which is easy to do with Alexey's ip command, using the addr subcommand), I'm not exactly sure whether this holds for non-IP addressfamilies. The virtual ethernet syntax lamp provided is not necessary anymore, and is basically ignored by the kernel, IIRC. However, given the possibility of adding multiple IP addresses to a single interface and the flexibility the routing code provides it should be possible to handle the tasks usually handled by subinterfaces, at least for the IP world.
