sysfs directories...
i was looking at /sys on my machine yesterday and i found something strange.
cd /sys/block/hda/device/block/device/block/device/block/device/block/... and that continues being almost infinite and recursive, it is normal ???
My Kernel Version is: 2.6.7-rc3
Cheers,

Both /sys/block/hda/device and the next element 'block' are symlinks, so it'll top out after 40 (enforced by vfs).

Consult your favourite Unix textbook and look up "symbolic links". Then look again at /sys/block/hda/device.

What does:
ls -l /sys/block/hda
show?

It's a bash trick when changing dir to a symlink:
hell:/sys/block/hda$ cd device hell:/sys/block/hda/device$ cd block hell:/sys/block/hda/device/block$ cd device hell:/sys/block/hda/device/block/device$ cd block hell:/sys/block/hda/device/block/device/block$ pwd /sys/block/hda/device/block/device/block hell:/sys/block/hda/device/block/device/block$ /bin/pwd /sys/block/hda hell:/sys/block/hda/device/block/device/block/device$ pwd /sys/block/hda/device/block/device/block/device hell:/sys/block/hda/device/block/device/block/device$ /bin/pwd /sys/devices/pci0000:00/0000:00:04.1/ide0/0.0
