Hey guys I''ve been beating my head on this for a few hours. Maybe it is
just a stupid configuration error you can point me at. First here is a

Collecting entropy from device_attach() times.
Hi.
I experimented a bit with collecting entropy from the time it takes for
device_attach() to run (in CPU cycles). It seems that those times have
enough variation that we can use it for entropy harvesting. It happens
even before root is mounted, so pretty early.
On the machine I'm testing it, which has minimal kernel plus NIC driver
I see 75 device_attach() calls. I'm being very careful

tabs, and the \001 character respectively.
In my service I am escaping those three
