Anyway, this is

Reviewed-by: Dario Faggioli <dario.faggioli@citrix.com>

if possible, with the above 'return 1' converted to 'return
EXIT_FAILURE' (either by resending or done upon commit).

If a maintainer wants to ack and commit this as is, my R-b still

won't stand in the way of a patch for something like this.

Dario
