Description
The old behaviour of GDAL is still useful, sometimes (e.g. to have a background of 0s instead of NULLs). Please add that option (instead of creating a new raster from scratch).

[-of format] [-a_srs srs_def] [-co "NAME=VALUE"]*
[-a_nodata value] [-init value]*
[-te xmin ymin xmax ymax] [-tr xres yres] [-tap] [-ts width height]
[-ot {Byte/Int16/UInt16/UInt32/Int32/Float32/Float64/
CInt16/CInt32/CFloat32/CFloat64}] [-q]

dst_filename:
The GDAL supported output file. Must support update mode access. Before GDAL 1.8.0, gdal_rasterize could not create new output files.I mean, it would be useful to specify an existing raster to burn the values on, so the user will be sure of the background value, extent and resolution.

can you please post a gdal_rasterize command that shows as this works? just to have a working example to work on.

No special option: from the command line, if you provide a file name, it will be used as a basis, if not it will be created
