It said case was sensitive depending on how you set the KERNEL setting.

so the flags above say CASE_SENSITIVE_SEARCH = false, so my saying
it IS case insensitive just like NTFS -- how is that incorrect?  I'm

	But we don't know (or do we?  not sure about what the flags relfect
above) -- if the flag in the kernel was toggled to "case sensitive for all 
wouldn't the above read File Case Sensitive Search=TRUE -- reflecting the kernel

If they can store case, and one tells the kernel to pay attention to case, wouldn't
it be case sensitive?

sorry, don't mean to confuse the issue, but I thought it was the kernel
setting that chose to be sensitive or not.
