This release includes the 3.13 version of the Linux kernel.
Apparently, the 3.13 release was chosen to ensure broader hardware support for this release.
This is indeed an important criteria when choosing a desktop kernel but isn’t when looking at servers setups where custom built kernels may be required or cloud computing scenarios where hardware does not matter.
This means that the Ubuntu kernel maintainers will have to do all the backporting work without any help from the community, for five years.I don’t know the people maintaining kernel patches for Ubuntu, but I’m skeptical with regards to their capability to properly maintain and backport fixes to a kernel that no other distribution will use.As a comparison, Red Hat chose the 3.10 longterm supported kernel for RHEL 7 which is yet to be released.Ubuntu 14.04 LTS (Trusty Tahr) has been released on April 17th 2014, thus this Long Term Support (LTS) version is brand new. Update (2015-10-05): Current personal recommendations: Your favorite distribution is not listed here? The major advantage of Ubuntu LTS releases is that they are supported for five years with updates. Updates from 2015-10-05 were written at that time but are only published now. Update (2015-10-05): You may send me an email directly now that the comments are closed.
Update (2016-04-20): Finally found the time to add updates from comments.They are also supposed to feature stable and mature software fitting in the current Linux ecosystem. But the recent choices prevent me from doing it anymore.Here are the reasons this is not the case today and will certainly never be the case with Ubuntu 14.04 LTS. I’m not criticizing Ubuntu developers nor their work at all.Update (2014-04-30): I’m definitely not against Ubuntu. I’m criticizing the choices made for this release and I try to explain why those are a bad fit for a LTS release.Taken one by one, those issues are almost OK, and could turn out not to be an issue at all.But combining that many of them in a release supposed to be sold to anyone as THE default distribution to run for the next two years should raise concerns.
