Other noexec lines are more related to program compilation,
I think that fetch configuration files to apply is a more generic case
for images.

The argument could work for do_install but there is a risk of overwrite
with other version of same config files, image-specific configuration
must be on higher priority, so there is a need to install them after
every other task (to eventually overwrite less specific config. files).

I could do the delVarFlag thing but I think that fetch image-specific file
is generic, and that the noexec flag here doesn't save much time anyway.
