I understood it that he just wants the one SSID and let his devices connect to the appropriate one. But his Linux system will always try the 2.4ghz first, so he ends up creating something like "mywifi24" and "mywifi5".
Personally, I would prefer doing the two separate names so I can know what I'm connecting to. Being a radio guy, I see it as two separate bands, two separate physical radios. I don't see a point in trying to give them the same name.
Of course, for my home environment, I'm pretty much using just 2.4, and I give all my access points the same SSID so I can "roam" between them. I suppose someone could want to be able to roam between 2.4 and 5ghz (I tend to use 5ghz for backhaul).
