Ubuntu 16.04 Reactions

I have misplaced my coffee mug. I’m glad to hear Ubuntu 16.04 LTS is out. “Codenamed ‘Xenial Xerus'” because computer people don’t already come off as a bunch of space cadets. Anyway, an under-caffeinated curmudgeon’s take:

The Linux kernel has been updated to the 4.4.6 longterm maintenance
release, with the addition of ZFS-on-Linux, a combination of a volume
manager and filesystem which enables efficient snapshots, copy-on-write
cloning, continuous integrity checking against data corruption, automatic
filesystem repair, and data compression.

Ah, ZFS! The last word in filesystems! How very exciting that after a mere decade we have stable support for it on Linux.

There’s a mention of the desktop: updates to LibreOffice and “stability improvements to Unity.” I’m not going to take that bait. No sir.

Ubuntu Server 16.04 LTS includes the Mitaka release of OpenStack, along
with the new 2.0 versions of Juju, LXD, and MAAS to save devops teams
time and headache when deploying distributed applications – whether on
private clouds, public clouds, or on developer laptops.

I honestly don’t know what these do, but my hunch is that they have their own overhead of time and headache. Fortunately, I have semi-automated network install of servers, Ganeti to manage VMs, and Ansible to automate admin stuff, so I can sit on the sidelines for now and hope that by the time I need it, Openstack is mature enough that I can reap its advantages with minimal investment.

Aside: My position on containers is the same position I have on Openstack, though I’m wondering if the containers thing may blow over before full maturity. Every few years some folks get excited about the possibility of reinventing their incumbent systems management paradigms with jails, burn a bunch of time blowing their own minds, then get frustrated with the limitations and go back to the old ways. We’ll see.

Anyway, Ubuntu keeps delivering:

Ubuntu 16.04 LTS introduces a new application format, the ‘snap’, which
can be installed alongside traditional deb packages. These two packaging
formats live quite comfortably next to one another and enable Ubuntu to
maintain its existing processes for development and updates.

YES YES YES YES YES YES YES OH snap OH MY LERD YES IF THERE IS ONE THING WE DESPERATELY NEED IT IS YET ANOTHER WAY TO MANAGE PACKAGES I AM TOTALLY SURE THESE TWO PACKAGING FORMATS WILL LIVE QUITE COMFORTABLY TOGETHER next to the CPANs and the CRANs and the PIPs and the … don’t even ask how the R packages work …

Further research reveals that they’ve replaced Python 2 with Python 3. No mention of that in the email announcement. I’m totally sure this will not yield any weird problems.
