I also noticed that vdr added itself to that group.
:; egrep ^vdr /etc/passwd
vdr:x:113:1013:added by portage for gentoo-vdr-scripts:/var/vdr:/bin/bash
Intresting.
I wonder how safe can that be for vdr to have read & write access to
every USB device?

Got it. Unless you have something else totally different to list here,
nevermind.
