ok, i see something strange here. As you mention, devfs is
mounted on startup, but then i see only the /dev/fd0 entry
in it. Apparently, entries such as fd0a and fd0c are created
when you try to access them e.g. with an "ls /dev/fd0c".
However, somehow the first call to mount fails:
# mount -o rdonly /dev/fd0c /fd
mount: /dev/fd0c: No such file or directory
# mount -o rdonly /dev/fd0c /fd
whereas the second one succeeds. Would it mean that the fd0c entry
is created, but somehow it returns an error to mount ? (and in
case, should this be fixed) ?
cheers
