These interface names are a new standard aimed at providing consistent (and persistent) names of network devices between different boots and Linux installs. There's a good amount of information and rationale here:

https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/

There's also the technical detail of the naming scheme here:

https://github.com/systemd/systemd/blob/master/src/udev/udev-builtin-net_id.c#L20

In short, for your case, the enpXsY signifies that it's a pci device (from the p), on pci bus X, in slot Y.

Ubuntu – Why is 12.04 removing the -server kernel flavour

As you noticed in the release announcements, the generic and server kernel flavors were merged for the 12.04 release in an effort to reduce the maintenance burden over the life of the LTS. The two kernel flavors actually only differed with regards to 2 major kernel config options: the default I/O scheduler and the preemption model.

This was discussed in detail on the Ubuntu Kernel Team mailing list

https://lists.ubuntu.com/archives/kernel-team/2011-October/017471.html

As noted in that thread, the default I/O scheduler changed from "deadline" to "cfq". However, anyone wanting to remain with the Deadline I/O scheduler could do so at boot time by setting elevator=deadline.

The preemption model changed from CONFIG_PREEMPT_NONE to CONFIG_PREEMPT_VOLUNTARY. At this time, I unfortunately do not have any performance benchmarks on hand to point you at. Hope this helps some. Thanks.

Ubuntu – Why does an Ubuntu Server have graphical.target as the default systemd target

Despite the name of the target, there is nothing graphical running on Ubuntu Server 16.04. You can run this command to check and compare it with your desktop distro if you like:

systemctl list-dependencies graphical.target

On my Ubuntu 16.04 server, I see that the targets depend on "display-manager.service", but no display manager is installed or running.

I expect Ubuntu servers are set this way for some kind of consistency, although I agree it's confusing.
