It was intentional.  The template scripts provide meaningful output
which I (after switching to lxc_create.c) was silencing, so I considered
that a bug.

Do you disagree?  Should we keep it silent?  Should we add an option to
lxc-create to dump template output either to a file or stdout or (if
unspecified) silent?
