:(

I thought it might be an advantage to record the file. But it isn't.
On upgrades portage calls: pkg_preinst, pkg_postinst, pkg_prerm,
pkg_postrm. So it first merges the new version and cleans the old one
later.

So for above pkg_preinst the file exists but it will be removed later
(if it wasn't modified) 

Next version: Use your old pkg_postinst but don't use WOKDIR but the
installed default file. (If you don't want to merge the default file to
ROOT you install it but move to T in pkg_preinst and to ROOT in pkg_postinst.)
