Culture assimilation
It will be interesting to see how things go regarding the assimilation of Lennart Poettering into IBM. Few companies make good on the promise of the continuing independence of recently acquired divisions, so unless Mr Poettering's behaviours are compatible with IBM's culture, I would expect a parting of the ways at some point, especially as I regard it as unlikely that he would be willing to make significant changes in his personal deportment to suit IBM. Similar considerations apply to other well-known personalities in Red Hat, such as Kay Sievers.
We live in interesting times for the future of the Linux software ecosystem.
