I have a half-baked cygport patch for texlive postinstall. I dropped it 
because I don't use cygwin's tex anymore, but it may have some value.

Packages put commands in /etc/postinstall/texlive. The first postinstall 
script runs and removes them, so subsequent postinsall scripts will see 
an empty workqueue. Ordering is done by assigning priorities to commands.
