So with devfs after you have connected a PCMCIA card, in some msec automagically the right devfs device is added to /dev/ or /devfs/?

With the current inode scheme nobody force you to put all blocks device in the same directory. I will use /tmp/myhd to be fast.
And the device-file lookup in the case of block devices is done only at mount time (I hope to be right here ;-) so it' s really not importatnt and it would be fast enough also with zillon of device in the same directory. In production server I mount hd once a month (the power usually go down once a month ;-).
