I'd change that to:

fix failure test if more than one fw file is in the fail list

Out of curiosity, which applications depended on this? I didn't see any apparent problems in the regression test suite.

Correct test

This change broke at least 4 ports, please run full tests

Address feedback. I'll reply to comments in a moment.

Reduce installer memory requirement to 256 MiB (QEMU's default was 128 MiB where the pkg OOM was observed).

Here is an example of how I made use of this code in iichid when it still was out-of-tree:

Oops, please forget the problem. The acpi infoactaully binding to iichid. So the bus can pretty easy to get the acpi information. But we still need a interface for setting a interrupt on the gpio side, right? Because we cannot use INTR_NG and bus_setup_intr need the iichid to be a children of gpio bus? I didn't see the code on the gpiobus have the ability to handle cross-tree reference. I see it needs either INTR_NG or a children of a gpio bus to enable it.

As brought up in OpenBSD the cleaner design would be to require the user to set a sticky O_BELOW flag on the file description with fcntl() to allow cross jail fd passing instead of hacking it into the file descriptor.

Well, I am not thrilled to introduce new name lookup semantics just to solve this problem. We could however make a sticky O_RESOLVE_BENEATH flag set in the file description with F_SETFL, and require it to be set when cross jail boundaries. That would be cleaner to implement since it doesn't require modification to the fget* interface. It is not as good with respect to compatibility, since it requires application changes, and then the file description referenced by the sender will also change (unnecessarily).
