If sudo is too much pain (and it must be since I have never really used it), 
just do
$ su -

I guess Oliver got what he had asked for :( Wine bug nothwithstanding ;)

Nope. I don't think that any decent distribution comes with world-writable raw 
hard drive devices. Even if "world writable" really means "everyone is in the 
group that has write rights".

My FC4 system (hand upgraded through the ages from RH7, through everything in 
between) sets the raw hard drive devices with read only for disk group, and 
no users are in that group anyway.

I'm puzzled as to what distribution would have user-writeable raw devices. I'd 
bet that someone somewhere messed things up for the users that were affected 
by that problem.

The "super restrictive" rights that you're talking about are *default* on 
every self-respecting distro. It actually takes some work to change them.

Cheers, Kuba

PS. Just in case: I don't buy the argument that having access to cd burner 
requires such hacks. Either manually set hdwhatever to be writeable by you, 
or (on udev systems) change udev device permissions in relevant config files.
