[GRASSLIST:4215] Re: mapset permission denied....

[Laurent BESSON]

There might be a workaround by creating the mapset on your hard disk and
using simlink to the files on the CD-ROM. The file that will have to be
writen on the disk will be wrote and the large file such as the raster
files will be on the CD-ROM.

OI know it might seem a little long to prepare but I think it will work.
