Granted, I made a sweeping generalization. Examples that come to mind
where a user needs direct write access to a device would include sound
and mixer devices, as well as CD/DVD-R devices, so discs can be burned
without suid binaries. (As you've pointed out, these should all be
taken care of in the UDEV scripts and pre-configured groups)
That all being clarified in detail, I still think Karl should refrain
from suggesting people change the ownership of devices that are a
mounted filesystem! (Actually, I think Karl should refrain from using
the Reply button entirely, but I'm just in a grouchy mood. I'll be
happy for small victories :) )
