ukuu - KSPlice updates your kernel on the fly, ukuu lets you pick your version

Black Lab Linux tests its new releases rigorously and generally tries to balance the demands of new hardware with what's tried, true and stable. When I asked lead developer Roberto J. Dohnert about ukuu (Ubuntu kernel update utility) this was his response :

Even so, a BLL user might find themselves with a piece of hardware that might be better supported on a non-LTS kernel. These are provided by Canonical, but are not tested through its HWE (hardware enablement stack) process which allows LTS release users to periodically update to more recent kernels which have been vetted. Ukuu simply allows for mainline, untested kernels to be installed. Look for the article on how to install it here and use this PPA (Personal Package Archive) :

After installation, the utility is found in Black Lab's System menu and after launching it, the utility begins to update sources and search for available mainline kernels. As shown in the picture below, the kernel that the current session, Live or installed, is running on is shown. The graphics give the rest of the information : if Tux is displayed in normal colors, it's a stable selection; if Tux is red, it's an unstable, or testing kernel.

Selecting Hide unstable or RC releases under Setttings hides the unstable kernels and only the stable mainline releases are shown :

Since I'm currently running in a Live session on an experimental release, I'm not actually going to install any of these 4.10 or 4.11 series kernels. But I have tested ukuu on a recently released IoT (Internet of Things) build to see if it would improve throughput on a TP-Link AC wireless card; it didn't, appreciably. But it was an interesting exercise and the IoT build was otherwise unaffected. 
To the reader, emphasis PC-Opensystems LLC : try this at your own risk. Black Lab Linux does not support using Canonical's mainline kernels in its consumer or enterprise builds. Roberto J. has mentioned that he might add the utility to future testing builds, but again, user beware!
Take care updating that kernel!

Black Lab Enterprise Linux vs Red Hat Enterprise Linux

Many customers have asked us.  What are the benefits of Black Lab Enterprise Linux vs Red Hat Enterprise Linux.  Below we have prepared a chart that outlines the differences between Black Lab Enterprise Linux vs Red Hat Enterprise Linux.

KSplice Uptrack - kernel updating is necessary, not optional

Even on Black Lab Linux, with its ever-vigilant development squad.
KSplice is an Oracle utility, primarily designed for Linux servers that need frequent patching but can't afford even the the momentary downtime of a reboot.
Roberto J. Dohnert has incorporated this utility at the desktop level to give the desktop user of his Enterprise Desktop a similar ability to update-minus-reboot. I'm using an earlier IoT (InternetofThings) build optimized for single-board systems, which doesn't include KSplice by default. So to install it, I downloaded the .deb from this link and installed it using Gdebi :

After installation, launch the program and from the Accessories -> System submenu in Xfce or Accessories menu in MATE, System Tools submenu. You will be prompted to enter the admin / sudo password and KSplice will begin searching its database :

After installation completes, the utility will open and show available updates to the kernel. Detailed view shows recent patches such as CVE-2017-7308, memory corruption in AF_PACKET socket options. The last sentence in the description of the Common Vulnerability Exposure is cuts to the heart of the matter "A local user could this flaw to elevate privileges." More information can be found here and  here. Linux, because of its basic security model, is a more hardened platform than Windows, but privilege-escalation exploits are the most persistent threat that a Linux server admin or (less likely) desktop user faces. And this is the end result :

Check out Black Lab, it's stable, well-designed and secure. And if you're using a different distro, download KSplice here. Linux has a smaller attack surface, and the average user is unlikely to be hacked, but ransomware and malware are constantly changing threats whose vector can't be anticipated; secure now doesn't necessarily mean secure always.
