But the upstream bug is closed as not a bug. So I don't know what to
make of that when user space tools fail but it's not a bug.

The work around I'm using is just make sure the all the .conf files in
/boot/loader have the change you want made already; it seems like this
is just being copied when making the .conf file for a new tree.
