The man who in every sense sits at the nerve centre of SUSE Linux has no airs about him. At 38, Vojtěch Pavlík is disarmingly frank and often seems a bit embarrassed to talk about his achievements, which are many and varied.
He is every bit a nerd, but can be candid, though precise. As director of SUSE Labs, it would be no exaggeration to call him the company's kernel guru. Both recent innovations that have come from SUSE - patching a live kernel, technology called kGraft, and creating a means for booting openSUSE on machines locked down with secure boot, have been his babies.
If there is one aspect in the open source world that can prove detrimental, it is companies that indulge in lock-in to the extent possible, according to Gerald Pfeifer, senior director of product management at SUSE.
Speaking to iTWire on the sidelines of SUSECon 2014, the third annual conference of the Germany-based SUSE Linux, which is being held in Orlando, Florida this week, Pfeifer (lictured above) did not mention any companies by name, though he did make a passing reference to Oracle.
"In addition to increasing service availability by updating critical kernel patches without rebooting, and reducing the need for planned downtime by patching frequently, SUSE Linux Enterprise Live Patching preserves security and stability by applying up-to-date patches," said Matthias Eckermann, senior product manager for SUSE. "It's a fully open source solution that features zero-interruption interaction with the system and a familiar deployment method. It's ideal for mission-critical systems, in-memory databases, extended simulations or quick fixes in a large server farm."
OpenSUSE 13.2 was released a week ago. As with the recent Fedora update, the latest release of openSUSE took a year to develop instead of the standard six months as the organization retooled its development practices.
SUSE Linux has now been around for over 20 years, and it’s still going strong. As usual, the latest release serves as a foundation for developing Novell’s SUSE Linux Enterprise and brings some significant new improvements. So let’s dive right in!
Because this is a UEFI Firmware system, the first step is to wrestle with with BIOS and UEFI configuration. Every OEM is different in this area, and sometimes even different models from the same OEM are different. The critical questions are:
How to UEFI boot from a USB stick
How to (optionally) disable UEFI Secure Boot
How to (optionally) enable Legacy Boot (MBR)
Will changes to the UEFI boot configuration be retained
I know from experience with previous Acer systems that there are two things you have to do in the BIOS to prepare for Linux installation. FIrst, you have to change the "F12 Boot Menu" option to 'Enable', so that that you can press F12 during startup and get to the Boot Select menu.
Second, if you want/need to change the UEFI boot settings, you will first have to set a "Supervisor Password" in the BIOS configuration. Once the password is set, you can disable Secure Boot and/or enable Legacy Boot as necessary.
After the installation process completed, and before I rebooted, I checked the UEFI boot configuration (efibootmgr -v). It was correct, with "opensuse-secureboot" defined and first in the boot sequence list. But then I rebooted and... it booted Windows. ARRRRGGGHHHH! NO! Acer doesn't do this kind of garbage, HP/Compaq does! I have two or three other Acer laptops around here, and the boot configuration is perfectly stable on them!
I rebooted and used F12 to get Boot Select, then selected openSuSE from there, and it came up ok. Then I checked the boot configuration again. Sure enough, the boot order had been changed back to have Windows Boot Manager first. Swine...
I rebooted again, and this time went into BIOS setup (F2). On the 'Boot' page, there is a 'Boot priority order' list, and "Windows Boot Manager" was right at the top of that list. There was nothing about "openSuSE" in the list, but there was a strange new entry for "HDD: WDE WD5000LPVX-22VOTTO", which is absolutely as clear as mud... I didn't recall seeing that entry when I was in the Boot menu the first time. I moved that item to the top of the priority list, crossed my fingers and rebooted.
Back in February SUSE unveiled a new means of live Linux kernel patching, kGraft, compared to the existing Ksplice. One month later, Red Hat unveiled their own solution that happened to be under development at the same time, Kpatch. Since both of them have been out, both have pursued mainline interests but neither one accepted upstream yet. Now a new live kernel patching solution is out that tries to take the best of both worlds.
This is the first release after the change in the openSUSE development mode, with a much shorter stabilization phase thanks to the extensive testing done in a daily basis in the rolling distribution used now as a base for openSUSE stable releases. The perfect balance between innovation and stability with the great level of freedom of choice that openSUSE users are used to.
It's Halloween week, and the big names in Linux are determined not to disappoint the trick-or-treaters. No less than three mainline distributions have released new versions this week, led by perennially-loved-and-hated crowd favourite Ubuntu.
Ubuntu 14.10, better-known by its nom de womb "Utopic Unicorn", hit the streets last Thursday. It appears to be a mostly update release, with more of the release announcement's ink devoted to parent-company Canonical's "Canonical Distribution of Ubuntu Openstack" than to Utopic's "latest and greatest open source technologies". Among those, the v3.16 kernel has been included, as well as updated versions of GTK, Qt, Firefox, LibreOffice, Juju, Docker, MAAS, and of course, Unity. Full details can be found in the official release notes.
