A major upgrade example: 14.4-RELEASE to 15.1-RELEASE

All commands should be run as root.

pkg update
pkg upgrade -Uy -r FreeBSD pkg
freebsd-update fetch
freebsd-update install
freebsd-update upgrade -r 15.1-RELEASE
freebsd-version -kru ; uname -mvKU
freebsd-update install
do not reboot the operating system – ignore the on-screen advice from freebsd-update
freebsd-version -kru ; uname -KU
/bin/sh
export abi=FreeBSD:15:$(uname -p)
export osversion=1501000
pkg-static -o ABI=$abi -o OSVERSION=$osversion -o IGNORE_OSVERSION=yes update
pkg-static -o ABI=$abi -o OSVERSION=$osversion -o IGNORE_OSVERSION=yes upgrade -Fqy
ignore all on-screen recommendations to force a bootstrap of pkg
pkg-static -o ABI=$abi -o OSVERSION=$osversion -o IGNORE_OSVERSION=yes upgrade -Fqy
pkg-static -o ABI=$abi -o OSVERSION=$osversion -o IGNORE_OSVERSION=yes upgrade -U -r FreeBSD-kmods
pkg-static -o ABI=$abi -o OSVERSION=$osversion -o IGNORE_OSVERSION=yes upgrade -U -g 'virtualbox-ose-additions*'
exit
upgrade the boot loader
disable loading of kernel modules for NVIDIA GPUs – you can use sysrc(8)
shutdown -r +10min "restarting with the upgraded kernel and boot loader"
after this restart, if software such as Discover invites you to upgrade software, ignore the invitation
freebsd-version -kru
freebsd-update install
be patient
freebsd-version -kru
if /usr/local/etc/pkg/repos/FreeBSD.conf includes FreeBSD and FreeBSD-kmods, change the names to FreeBSD-ports and FreeBSD-ports-kmods
pkg bootstrap -fy
pkg upgrade -fFqy -r FreeBSD-ports -r FreeBSD-ports-kmods
pkg upgrade -fFqy -r FreeBSD-ports -r FreeBSD-ports-kmods
pkg upgrade -fU -r FreeBSD-ports -r FreeBSD-ports-kmods
if reinstalling all third-party software is not possible, install misc/compat14x
if the previous run of freebsd-update install asked you to rerun the command, do so
shutdown -r +10min "restarting with the upgraded userland"

Essentially, two commands:

pkg upgrade -Fqy
pkg upgrade -qUy && shutdown -r +30 "restarting with an upgraded kernel"

– it was not necessary to repeat the first.

Please note

This is not an encouragement to perform upgrades before official announcements.

For the second command, I used the --quiet and --yes options only because in this case – a test machine in VirtualBox – I had confidence that installing packages would have no adverse effect. You should never combine those two options without knowing exactly what you're doing.

It was a simple upgrade, not a minor or major upgrade.

… bzfs is a CLI for reliable ZFS snapshot replication using zfs send/receive and SSH. It is meant for the boring-but-important corner of infrastructure where "probably replicated" is not the vibe.

The main bit in this release: bzfs can now drive recursive resumable ZFS stream packages …

Better laptop sleep and Wi-Fi support make the beastie more portable-friendly, but getting beyond the shell remains a DIY job

Tested with a Core i5-based ThinkPad X220.

Surprisingly:

… The handy optional desktop-installer script is still available, but as far as we can tell, it hasn't been updated for version 15.1 yet. In our testing, it couldn't correctly install a working desktop, and whatever desktop we tried, it failed without giving any visible error. …

Worked around, through manual installation of software, but I'm surprised that it happened.

A sequence of commands:

pkg upgrade -Fqy
pkg upgrade -U
pkg update
pkg upgrade -Fqy
pkg upgrade -U

Normally

If updates are available – and if there are no solver conflicts in response to the first command:

all updates will be listed following the second command.

With the upgrade of pkg from 2.7.5 to 2.8.0_1

The second command is followed by:

a prompt to run pkg update
"Your packages are up to date."

– and the packages are not necessarily up-to-date.

For the truth, you must run pkg update and then again pkg upgrade …

No response to normal keyboard or mouse input at ttyv8, so login to a desktop environment is impossible.

Using Virtual Machine Manager to key Ctrl+Alt+F2 (pictured below) does not switch to ttyv1.

Weird.

This machine did previously work.

Comparison

I'm reminded of a bug that sometimes prevents use of vt(4) in VirtualBox, however I doubt that the root causes are the same:

FreeBSD-RELEASE in VirtualBox: vt no longer visible when switching away from a desktop environment at ttyv8 : r/freebsd

Anthropic's Claude Mythos Launch Is Built on Misinformation

He misinforms his readers:

… Nicholas Carlini published a 15-round reverse shell exploit here, …

– false. Devansh:

links to the post-CVE work by Calif
misattributes the work to Carlini.

Carlini used Claude Mythos before publication of CVE-2026-4747. The work by Anthropic is properly described here:

Claude Mythos Preview \ red.anthropic.com (2026-04-07)

– unfortunately, not referenced at https://www.cve.org/CVERecord?id=CVE-2026-4747.

As a direct consequence of misinformation by Devansh, we have a somewhat misleading article by Jessica Lyons:

Anthropic Mythos shaping up as nothingburger • The Register

– and so on, and (sigh) I see the word "slop" in response to the article …

…

Mach IPC, launchd (replaces /sbin/init), configd/IPconfiguration (replaces netif), IOkit (replaces devmatch, devd). Resulting in automatic graphics detection, automatic networking with state change handling, service supervision, parallel startup to name a few things. I have other ideas beyond Darwin components like porting smb3 from illumos that I have been brewing about for a long time. New frameworks for jails, bhyve. The equivalent of dockerhub for jails. Management tools comparable to this https://www.hexbsd.org (an earlier creation of mine). A revived NAS appliance. A Gershwin on NextBSD image (desktop appliance).
