NetBSD has a new sysctl infrastructure

Jay Fink writes “Andrew Brown has committed a complete rewrite of the
kernel’s sysctl infrastructure. Some of the new features
are:

• The kernel knows about (but does not currently use) the name to
  number mapping for each node. Auto-discovery of the tree is now
  possible.
• Nodes can now be added to the tree by lkms, device attachment
  routines or at securelevel 0 from the command line via the
  sysctl binary.
• Adding new nodes (or subtrees) to the sysctl tree is now much
  simpler.

Andrew also cross compiled
150 kernels for 30 architecures
to see where some problems might come up. Additional
information can be found in Andrew’s email to
