No, I'm not sure. But, in 4.10, with /dev already populated with an
entry for fd0, I could plug the floppy into a running machine and then
mount it, no problem. So I'm thinking that if can either create an entry
for /dev/fd0 during or shortly after boot time, or get devfs to rescan
for devices, then it should work on -current also. I occurs to me that
rescanning might wreak havoc with operations already using other
devices, like a disk write or something, so the first option may be
preferable.
This is not a critical issue, but falls more in the category of "Gee, I
wonder if i can (fill-in-the-blank)" sort of thing.
BTW, thanks for your reply...
