Not sure anymore, I'll re-run my test.
Ok. It seems to be even more interesting, but is probably even better
pointing to the malicious code

For simplifying the output I used now

    perl -naE 'say "@F" if /^DEFINE DUMPTYPE foo/../^}/ and /SCRIPT|DUMPTYPE/'

Given my config example from the recent post (set the script in "foo"):

    $ amadmin foo config --no-default | perl …
    DEFINE DUMPTYPE foo {
    SCRIPT pre-dle
    DEFINE DUMPTYPE foo-foo {
    DEFINE DUMPTYPE foo-foo-foo {

    $ amadmin foo config | perl …
    DEFINE DUMPTYPE foo {
    SCRIPT pre-dle
    DEFINE DUMPTYPE foo-foo {
    SCRIPT pre-dle
    DEFINE DUMPTYPE foo-foo-foo {
    SCRIPT ""

So we're right both. With '--no-default' it does not propagate at all,
but it does one level w/o '--no-default'.

This matches the behaviour I watched but didn't investigate further,
because I thought it was confused by too much inheritance: My actual
production config has the script declaration in the last but one level
*and* worked as expected.
