 Some Network Attached Storage (NAS) filers with snapshot backup on volume
 level do not allow to exclude specific file types or directories to be
 excluded from backup.
 If GRASS data DB is stored on such a storage system, temporary files can
 grow the snapshot file significantly until a point where available space
 is used up by backup files (how fast that happens depends on the snapshot
 frequency of course, and the time they are preserved).


 Currently, it is not possible to redirect all temporary data to other
 storage locations. Would be great to have an environment variable that
 allows to specify a path (directory) where all temporary data will be
 stored.


 Might be necessary to make a subdirectory per mapset within that
 directory... (Maybe an 8.0 thing?)
