Block size 4096 will be used.
Linux 2.6.11-cko2 is detected.
Uuid 74aecbaf-6013-4b9f-9006-691d55f26940 will be used.
Reiser4 is going to be created on /dev/hdd5.
(Yes/No): Yes
Creating reiser4 on /dev/hdd5 ... done
gremlin mnt # mount -t reiser4 /dev/hdd5 /mnt/seagate/
gremlin mnt # df

so it's 20646MB on ext3 versus 19930 with reiser4
I used reiser4progs 1.0.4 under 2.6.11-cko2 kernel
