 There is some issue in G7:g.findfile interface or implementation.

 If you list elements, `rast` is present:

 {{{
 GRASS > g.findfile -l
 List of available elements:
   rast      (raster map(s))
   rast3d    (3D raster map(s))
   vect      (vector map(s))
   oldvect   (old (GRASS 5.0) vector map(s))
   asciivect (ASCII vector map(s))
   labels    (paint label file(s))
   region    (region definition(s))
   region3d  (3D region definition(s))
   group     (imagery group(s))
 }}}

 But look for the `elevation` with `element=rast` and you get nothing:

 {{{
 GRASS > g.findfile element=rast file=elevation
 name=
 mapset=
 fullname=
 file=
 }}}

 `element=cell` works as well as `element=fcell`:

 {{{
 GRASS > g.findfile element=cell file=elevation
 name='elevation'
 mapset='PERMANENT'
 fullname='elevation at PERMANENT'
 file='.../PERMANENT/cell/elevation'
 GRASS > g.findfile element=fcell file=elevation
 name='elevation'
 mapset='PERMANENT'
 fullname='elevation at PERMANENT'
 file='.../PERMANENT/fcell/elevation'
 }}}

 What is the right behavior? It seems that there is a difference between
 element and type, is this true? What is appropriate for `g.findfile`? What
 would be the value for `file` key if `g.findfile` would support
 `type=rast` etc. instead of `element=cell|fcell|dcell`? What about 3D
 rasters?
