Swabber profiling using strace slows builds down, therefore it would useful to be able to have the strace wrapper run only for certain recipes (i.e. the ones the user cares about). We could do this with a configuration variable, SWAB_RECIPES? such that when this variable is set the image-swab class will not use the strace wrapper for recipes which are not set in this variable.
Swabber is not a viable tool
