Figured this out... by some tweaks to the REST magic words needed.
In case it helps someone else, here's how it finally worked:
1. Delete the existing coverage (if any)
curl -s -o /dev/null -k -u %CRED% -XDELETE
%HOST%/rest/workspaces/%WS%/coveragestores/%COV%?recurse=true
2. Create the coverage store from the server-resident file (which
automatically creates a coverage as well)
curl -f -k -u %CRED% -XPUT -H "Content-type: text/plain" -d "file://%FILE%"
%HOST%/rest/workspaces/%WS%/coveragestores/%COV%/external.geotiff
3. Set the SRS and enable the coverage:
curl -s -k -u %CRED% -XPUT -H "Content-type: text/xml" -d
"<coverage><srs>EPSG:3005</srs><enabled>true</enabled></coverage>"
%HOST%/rest/workspaces/%WS%/coveragestores/%COV%/coverages/%COV%
(Of course this was done in a cmd script with oodles of baroque error
checking - exercise left for the student)
On a side note, once again I needed to puzzle out the differences between
the GeoServer internal information model (as revealed by the REST API) and
the GUI terminology (which hides some of the internal concepts such as
FeatureTypes and Coverages). I always feel that a Logical Domain Model
diagram would help with understanding this, and perhaps also some mention
in the UI docs about what is going on under the hood.
