I was able to access the pen having restarted floppyd with the

removing and reinserting the pen no access was possible.
So I wonder if it is correct for floppyd to use the static /dev/sda1 or
whatever device, perhaps the correct device is the devfs one. And
possibly floppyd does not handle devfs very well.
With devfs /dev/sda1 is (or should be!) a symlink to the actual device.
Right. It might be, I don't have the client here to test. The script
that runs at boot does this:
mknod /dev/sda b 8 0
mknod /dev/sda1 b 8 1
chmod 666 /dev/sd*
floppyd -d /dev/sda1
But it would probably be better to do somthing like
floppyd -d /dev/scsi/.../part1
Either that symlink is not (yet?) created, or floppyd does not handle
symlinks to devices.
Yes, it could be a timing problem. Floppyd is a bit of white area on my map.
Check if /dev/sda1 actually exists after unplugging and re-plugging the
USB key. That is not always the case - guides for booting off of USB
keys tend to include adding the following after loading the USB modules
to "wakeup" the device:
/bin/sleep 5
/sbin/sfdisk -R /dev/sda || true
Yes, good point. But with the device /dev/sda1 being totally static it
is there all the time. But perhaps just staring out into the wild blue
yonder rather than at the usb pen.
(the fallback to true I invented myself, because it may fail and that is
fatal in an initrd)
Nice.
