What a coincidence! I just had to reboot lkishalmi.eu this afternoon after ~20 days of uptime in order to apply kernel and docker changes. I briefly thought when would we use the Live Kernel patching feature which is one of the big features in the 4.x series of the Linux Kernel… Well I sighed and went on with the reboot.

In the evening I’ve just read read this post on Phoronix. Canonical makes Ubuntu live patching available for 16.04 64bit kernels. Much better it is free up to 3 instances for Ubuntu Community members. So from now on I enabled Ubuntu LivePatch on lkishalmi.eu
