  Reporter:  sbl          |      Owner:  grass-dev@…
      Type:  defect       |     Status:  new
  Priority:  normal       |  Milestone:  7.0.3
 Component:  Raster       |    Version:  svn-releasebranch70
Resolution:               |   Keywords:  r.external.out
       CPU:  Unspecified  |   Platform:  Unspecified

Comment (by sbl):

 This issue applies equally to r.external, where links are allways
 converted to absolute paths
 (https://trac.osgeo.org/grass/browser/grass/trunk/raster/r.external/main.c
 lines: 162-170).

 Both r.external and r.external.out are therefore practically unusable in
 mixed environments where data can / should be accessed from both Windows
 and Linux. Maps linked with r.external / r.external.out will not be
 readable across platforms, because absolute paths differ (of course
 directory delimiters differ as well).
