While this will work, it is quite dangerous if the sg driver can see any
disks:  access to /dev/sg* for users will allow them to read / write /
format any SCSI device attached to the bus (although obviously if they
only have permissions on /dev/sg0 they can only do nasty things to the first
device).  I usually make the cdparanoia binary (and cdrecord, etc.) setuid
to root instead, and only allow root to open /dev/sg*, that reduces the
risk.  I suppose it is OK to leave things as they are for a single user
IDE-only system though.
