Yann,

The client must convert to absolute path because the daemon has no idea
what the cwd is of the client.  This is true even when the client and
server run on the same machine.  i.e.:

    rrdtool update 1.rrd N:1:2
    cd elsewhere
    rrdtool update 1.rrd N:1:2

You could:

 * use the same file hierarchy on client and server

 * speak to the daemon directly from your application
