Re: rpm %post - check for version being upgraded

This is a bit of advanced rpm trickery that probably falls in the

Short version:
How do I query in %post, when executed during an upgrade,
for the version we are upgrading from?
Urgh.
Long version:
A custom rpm (that OLPC's XS uses to manage configuration) needs to
nuke a dynamically generated config file -
/etc/udev/rules.d/70-persistent-net.rules - _only once_. Before
version 0.5 of the pkg, the script that drove the device naming was
subtly wrong.
Why "only once"? Better/much more robust/easier stomp on data
_always_. Perhaps do it with version 1.2.3-0.fc11, and (after a suitable
time) release 1.2.3-1.fc11?
