I guess things need to be brought in sync. The file I quoted from
was for 2006, so the change was made at least that long ago. It is
the same in the 2009/04/06 version. But I did forget to include this
comment from the end of the floppy device section:
NOTE: The letter in the device name (d, q, h or u)
signifies the type of drive: 5.25" Double Density (d),
5.25" Quad Density (q), 5.25" High Density (h) or 3.5"
(any model, u). The use of the capital letters D, H
and E for the 3.5" models have been deprecated, since
the drive type is insignificant for these devices.
After some more digging I've came to pretty much the same conclusion. So
after a few years of general inactivity, I'm going to update floppy with the
current device names, and I'll see if I can the upstream to update the fd(7)
man page. But until the updated floppy makes it way into the Fedora branch
of util-linux-ng, running MAKEDEV is the only workaround.
