We made the following additions and updates to our distribution images and netboot installers:

Here are some highlights from each.

Alpine Linux

This includes an important security fix for openssl (CVE-2020-1967).

CentOS 7

  • Python 3 is now available. Installing the python3 package gives you the Python 3.6 interpreter.
  • bind has been rebased to version 9.11.
  • chrony has been rebased to 3.4.
  • Since release 1503 (abrt>= 2.1.11-19.el7.centos.0.1) CentOS-7 can report bugs directly to bugs.centos.org.

Fedora 32

Updated packages include: python 3.8, ruby 2.7, and gcc 10. Most Pythron 2 packages have been removed from Fedora, since Python 2 is end of life. A legacy python27 package is provided for those who need it.

NetBSD 8.x

  • httpd(8): fixed various security issues
  • named(8): stop using obsolete dnssec-lookaside.
  • Various kernel memory info leaks fixes.
  • Updated expat to 2.2.8.
  • Accepts root device specification as NAME=label.

NixOS

Support is planned until the end of October 2020. Among numerous added and updated packages, the following version updates were made to core packages:

  • gcc: 8.3.0 -> 9.2.0
  • glibc: 2.27 -> 2.30
  • linux: 4.19 -> 5.4
  • mesa: 19.1.5 -> 19.3.3
  • openssl: 1.0.2u -> 1.1.1d

Ubuntu 20.04

Ubuntu 20.04 offers zfs version 0.8.3. A few new zfs features include:

  • Native Encryption (with hardware acceleration enabled in Focal)
  • Device removal
  • Pool TRIM
  • Sequential scrub and resilver (performance)

In 20.04 LTS, the python included in the base system is Python 3.8. Python 2.7 has been moved to universe and is not included by default in any new installs. The /usr/bin/python executable is not available in new installs by default.

It doesn’t seem to be mentioned anywhere on the net, but the value of the kernel.pid_max sysctl was bumped from 32768 to 4194304. We mention it in case someone is surprised by very large process IDs in their ps output.

Installation

Our distribution images and netboot installers are available from the management console of any Prgmr.com VPS.

Note that all of the updates other than CentOS 7 and NetBSD are only available to customers with a VPS using HVM virtualization. NetBSD is only available to customers with a VPS using PV virtualization. To check the virtualization mode of existing services, log in to the management console, select “system details”, and check the virtualization mode.
