The first three patches in this series look OK to me so far.

There is some conflict with Jani's --config command line argument patches,
but that should be easy/generic to fix.

I'll try to review the next 3 patches in this series this week; this
message should serve as a heads up for people interested in this series
that its next on my agenda after Jani's config file patches.
