Hello world,
I've installed linux on a 10gb nilfs2 root partition /dev/sda2. When I
boot into it nilfs_cleanerd won't run

root:/home/andy# ps aux | grep nilfs_cleanerd
root      1497  0.0  0.0   5456   592 pts/0    S+   17:18   0:00 grep nilfs_cleanerd

If I start nilfs_cleanerd with a command it quits with no error message
at the command prompt but it leaves this in the system log

Nov  5 17:18:05 eccles nilfs_cleanerd[1495]: start
Nov  5 17:18:05 eccles nilfs_cleanerd[1495]: cannot open nilfs on (null): No such file or directory
Nov  5 17:18:05 eccles nilfs_cleanerd[1495]: cannot create cleanerd on (null): No such file or directory
Nov  5 17:18:05 eccles nilfs_cleanerd[1495]: shutdown

If I pass it different options the only thing that changes is the error it dumps in the system log

root:/home/andy# nilfs_cleanerd /

Nov  5 17:19:02 eccles nilfs_cleanerd[1503]: start
Nov  5 17:19:02 eccles nilfs_cleanerd[1503]: cannot open nilfs on /: Inappropriate ioctl for device
Nov  5 17:19:02 eccles nilfs_cleanerd[1503]: cannot create cleanerd on /: Inappropriate ioctl for device
Nov  5 17:19:02 eccles nilfs_cleanerd[1503]: shutdown

root:/home/andy# nilfs_cleanerd /dev/sda2

Nov  5 17:19:26 eccles nilfs_cleanerd[1505]: start
Nov  5 17:19:26 eccles nilfs_cleanerd[1505]: cannot open nilfs on /dev/sda2: No such file or directory
Nov  5 17:19:26 eccles nilfs_cleanerd[1505]: cannot create cleanerd on /dev/sda2: No such file or directory
Nov  5 17:19:26 eccles nilfs_cleanerd[1505]: shutdown

root:/home/andy# cat /etc/mtab
/dev/sda2 / nilfs2 rw,gcpid=1292 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
devpts /dev/pts devpts rw,gid=4,mode=620 0 0
shm /dev/shm tmpfs rw 0 0
/dev/sda1 /mnt/windows ntfs rw,umask=0 0 0
/dev/sda7 /home reiserfs rw 0 0
/dev/sda3 /mnt/lfs btrfs rw 0 0

The only way I can get garbage collection to run is if I reboot into
a different partition and mount it from there.
