OpenStack Liberty is the 12th release of the open source software collaboratively built by a large number of contributors around the OpenStack.org project space. The RDO community project ( https://www.rdoproject.org/ ) curates, packages, builds, tests and maintains a complete OpenStack component set for RHEL and CentOS Linux and is a founding member of the CentOS Cloud Infrastructure SIG ( https://wiki.centos.org/SpecialInterestGroup/Cloud ). The Cloud Infrastructure SIG focus on delivering a great user experience for CentOS Linux users looking to build and maintain their own onpremise, public or hybrid clouds. In addition to the comprehensive OpenStack services, libraries and clients, this release also provides Packstack, a simple installer for proof-of-concept installations, as small as a single all-in-one box and RDO Manager ( https://www.rdoproject.org/RDO-Manager ) , an OpenStack deployment and management tool for production environments based on the OpenStack TripleO project. --- QuickStart: Ensure you have a fully updated CentOS Linux 7/x86_64 machine, and run : sudo yum install centos-release-openstack-liberty sudo yum install openstack-packstack packstack --allinone For a more detailed quickstart please refer to the RDO Project hosted guide at https://www.rdoproject.org/QuickStart For RDO Manger consult https://www.rdoproject.org/RDO-Manager page. RDO project is closely tracking upstream OpenStack projects using the Delorean tool[1] which is producing RPM packages from upstream development branches. Since the previous OpenStack Kilo release, RDO is participating in the Cloud SIG and using CentOS provided infrastructure. Towards the end of developement cycle packages are imported into CentOS Cloud SIG buildsystem[2] and get eventually published in Cloud SIG repositories[3]. [1] http://trunk.rdoproject.org/ [2] http://wiki.centos.org/HowTos/CommunityBuildSystem [3] http://mirror.centos.org/centos/7/cloud/x86_64/ Getting Help: The RDO Project provides a Q&A service at ask.openstack.org, for more developer oriented content we recommend joining the mailing list at https://www.redhat.com/mailman/listinfo/rdo-list. Remember to post a brief introduction about yourself and your RDO story. You can also find extensive documentation at https://www.rdoproject.org/Docs. We also welcome comments and requests on the CentOS Mailing lists ( https://lists.centos.org/ ) and the CentOS IRC Channels ( #centos on irc.freenode.net ), however we have a more focused audience in the RDO venues. To get involved in the OpenStack RPM packaging effort, see https://www.rdoproject.org/Get_involved and https://wiki.centos.org/SpecialInterestGroup/Cloud Join us in #rdo on the Freenode IRC network, and follow us at @RDOCommunity on Twitter. And, if you're going to be in Tokyo for the OpenStack Summit next week, join us on Wednesday at lunch for the RDO community meetup ( http://sched.co/4MYy ). I'd like to thank all RDO developers and CentOS Project for their effort and support resulting in this release, especially dmsimard - for continuously improving RDO CI jpena - for keeping Delorean service up and running jruzicka - for the rdopkg auto-magic number80 - for countless reviews and packaging wisdom social - for puppet module mastery trown - for leading RDO Manager side of the show!

But coming back to negative part (which is about almost any Linux distribution). These often reboots started in my recollection around 2.6 kernel which is long ago. Already then one of my friends started calling Linux "Lindoze" apparently stressing you need to reboot it often, like MS Windows. I would suggest to take his label with a grain of salt, as he is the one who also used funny name for another well known system, after Oracle bough out Sun Microsystems he called Sun-Oracle "snorkel" (as if you pronounce it awfully fast). This was what made first step to "similarity" at least in one respect of Linux to MS Windows. Is systemd yet another step? No comment from me, as at some point I decided to not be on any side of apparently awfully polarized on this issue community. ;-) Valeri Valeri Galtsev Sr System Administrator Department of Astronomy and Astrophysics Kavli Institute for Cosmological Physics University of Chicago Phone: 773-702-4247 ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

No. If anything, systemd handles upgrades better than SysV init, since it handles re-execing better. Please stop spreading FUD. Most likely the glibc and openssl updates are what people are talking about. Doesn’t require a reboot, just restarting all the services that might have those libraries loaded. -- Jonathan Billings ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Please stop spreading FUD. What FUD? It adds *binary* logfiles, readable only with a separate program; when I restart a service, it does not *tell* me what's going on, just worked or didn't, so I don't know, if it fails, where, the messages from journalctl are extremely unhelpful, and when it boots, if I want to watch, it tends to hide much info.

It's much less informative in most ways in helping me solve problems. Well, looking back, during kernel 2.6 there was no systemd at all. But! That was the time where udev and dbus came into the boot cycle. IMHO, the intrinsics between glibc (always a cause for refresh of initrd and full reboot) and udev where the start of the "reboot often". Later on came dbus from the pure app-message-bus to the monster (kdbus?) that it is now, adding in its own dreg of dependencies and making the boot cycle unclean in itself. The mess we have now, is not the work of just one change. What was the rationale to get udev into boot? -- Handling the ever changing mess of plugable, switchable hardware. Not born and bred for servers, but for mobiles (phones, tablets, laptops). Who was the one that decided that "one-size-fits-all" and put that into server environment? What was the rationale to let dbus near the system start at all? -- Again mobile development. Same as before who was the one that thought, "nice, lets fuck up the servers even more with that". Systemd was just the latest development, and not the worst. Yes, it could have gone better, and some of the devs have had more head-in-the-clouds than feet-on-the-ground. Looking back, systemd is the only "big" change since 2.6 that makes sense for servers. It's surrounding scene, however, does not make much sense for servers. Journald is a mess, but solveable -- install a "real" syslogd and get on with life. The mess that is networking, well, that could have / should have gone better. Lets not cast out the babe with the wash-water, through. That the difference between Linux servers and MS-Windows server got smaller is a matter of both sides. The difference between a MS-Win 2k server and a MS-Win 2016 server is much more than just 16 years. MS-Win 2016 kann be headless. A break-trough, 2012 was partly there. What was the jump forward for linux servers in this 16 years? We have lost some of the original Unix way: every tool should do one thing, and should do it right, be as small and as fast as possible.
