Hmmm... wouldn't it be better to just export flush and fua instead of
ignore_*?  So that the admin can turn things on and off as [s]he seems
fit?  Also, it might be better to export them in a single attribute,
say cache_control or something.  Only subset of the combinations make
sense anyway - none, flush, flush_fua.

Thanks.
