(hangs indefinitely) (note that 2609 MB is way too much to fit on the 250 MB memory stick, but that was the point, right :)) dannym@pyramid: /mnt/tmp/dannym/> df /dev/sda1 /dev/sda1 242948 242824 124 100% /mnt/tmp 'ps aux |grep cp' hangs. dmesg says: [ 84.597446] reiser4: sda1: found disk format 4.0.0.
