Option --allow_emulated_drives enables addressing of pseudo-drives
which get emulated on top of a regular data file or a block device.
which get emulated on top of filesystem objects. Regular data files and
block devices result in pseudo-drives which behave much like DVD-RAM.
If the given address does not exist yet but its directory exists, then
it gets created as regular file.
Other file types like character devices or pipes result in pseudo-drives
which behave much like blank DVD-R.
The target file address is given after prefix "stdio:".

Warning: Superusers must take care not to spoil their hard disk via its raw
block device (like /dev/hda or /dev/sd0).
Pseudo-drives behave much like DVD-RAM. They allow -dummy, nevertheless, and
their reply with --tell_media_space can be utopic. If the given address does
not exist yet but its directory exists, then it gets created as regular file
as soon as a write operation occurs.
Note: -dummy burn runs touch the file.
Addresses of the form "stdio:/dev/fd/<number>" are treated special. The
number is read literally and used as open file descriptor. With
dev="stdio:/dev/fd/1" the normal standard output of the program is
redirected to stderr and the stream data of a burn run will appear on stdout.
Not good for terminals ! Redirect it.
Pseudo-drives allow -dummy. Their reply with --tell_media_space can be utopic.
Note: -dummy burn runs touch the file but do not modify its data content.
