mount block devices with sysfs?
 

i want to know if i can mount my hard disks using sysfs
/sys/block/hda/hda1 is not reported as a block devices
kernel 2.6.2 says that devfs is now obsolete, so i'm left wondering why my hard disks and floppy disk are still mounted using /dev
what parameters do i need to use /sys for this?
thanx
