AFAIK, no.  Hopefully someone will prove me wrong.
What I try to do is the following:
- try to only modify files in /etc/config (not always possible,
  e.g. /etc/passwd).
- if I have to modify a file outside /etc/config, then try and modify
  it in the OpenWRT source from which you build the firmware, so the
  same change will be applied to the next firmware I build.
That doesn't solve all problems, but I find it's a good start to
maintain sanity.  Still, OpenWRT's story w.r.t upgrading a system is not
its strongest point.
