Comment 1 for bug 1623413

Additional feedback:
Upgrades of the contrail package do not work without manual intervention.
Removing the package and then installing the package works. Clean installs also work.

However there is big this way of packaging would not survive a kernel upgrade without manually creating the symlinks after that.
In that regard packaging is really broken.

eBay thinks they should be able to do the following without manual creation of symlinks, running depmod etc.
1) upgrade the package
2) upgrade the kernel

According to eBay, weak modules would solve this because they think that functionality intended for this problem.
