[BUG]? Udev, USB Disks and /dev special files

[Eric Bambach]

Hello,
	First, please pardon me if this is a known problem,fixed or I am posting to 
the wrong list. Second please CC me as im not subscribed.

	I have an interesting situation. It seems /dev entries,specifically special 
devices are not interpreted by the kernel across UDEV mounted devices. My 
hardware. One IDE to USB 2.0 enclosure with an 80GB HD with kernel 
2.6.7-gentoo-r8 . I have configured udev to name my device /dev/usbcage and 
its partitions /dev/usbcage1...etc.

	I am installing gentoo on this disk and was having trouble because /dev/null 
was neither readable nor writeable, same for other special files, random, 
zero, etc. Even a chmod 777 would not fix the problem. Turns out that if I 
unmount /dev/usbcage and mount it as its proper name /dev/sde1 then this 
problem disappers. Same permission, even scaled back to 666. Is this an issue 
with the kernel, Udev, or both? Can't the kernel interpret /dev entries 
across symlinks? Should I submit this as a bug to LKML?

	Let me know if anyone would like more info.
