That's not good is it. Wonder why procps does that... Hmmm.

That's great - I'll grab and try. - Did you change the makefile for make
config all so that it does a userspace build with a different KERNELDIR
than the module build? Or does that still have to be done in two
separate stages still as we did "by hand" before?

Aaaah. OK.

Neat thing is, (I think - can't see a downside here), I can use enbd as
a drop in replacement when I've got the new version built and tested as
everything else is the same.

Kind regards
