Comment (by sbl):

 Partly fixed I would say:

 However, groups from other mapsets are still not fullly useable e.g. in
 i.cluster.

 {{{
 grass77 ./nc_spm_full_v2alpha/stefan/ --exec i.cluster group=mygroup at user1
 subgroup=subgroup signaturefile=sign classes=3

 Starting GRASS GIS...
 Cleaning up temporary files...
 Executing <i.cluster group=mygroup at user1 subgroup=subgroup
 signaturefile=sign classes=3> ...
 WARNING: Subgroup <subgroup> doesn't have any raster maps
 ERROR: Subgroup must have at least 2 raster maps
 Execution of <i.cluster group=mygroup at user1 subgroup=subgroup
 signaturefile=sign classes=3> finished.

 }}}

 In addition, i.cluster seems to try to write to the imagery group
 directory in the other mapset (the signature file), so further adjustments
 downstreams seem to be required...
