  s6-rc-compile should never dereference symlinks; if it does, it's a bug.
It will copy hierarchies under data/ and env/ verbatim.
  It also copies data and env themselves verbatim if they are
symlinks, but I recommend not relying on that behaviour. Better make
a real data/ subdirectory and all the symlinks you want under it.

  Gah. One of the main objectives of s6-rc is precisely to cleanly
handle early services such as udev. You should be able to run udevd
as a longrun as soon as you need it; what problems did you encounter?

  I'm very interested in any examples of scripts that work with a
"traditional" rc system and don't with s6-rc. It's the exact kind of
data I need to polish the system and make it suitable as a drop-in
