Comment 4 for bug 121341

We get so many crashes which are due to Python modules not being functional at all during dist-upgrades (or after a partially failed one), that we really need to fix this properly once and for all. We should investigate the following possibilities:

 * Drop all the symlink magic and instead add the non-version-dependent module directories to the default module search path of all python versions. (My prefered solution)

 * Do all the symlink removal and updates in postinst only, so that it happens atomically.
