We discussed Eurobhyvecon during EuroBSDcon, #FreeBSD Chromebook CoreBoot and UEFI support, migrating to Sylve, a new utility to save and restore PCI state, Intel CPUs and the vmap_pfn() bug, and more!

AS201379, part 5: joined EVIX (an IXP whose fabric is VXLAN tunnels, so no port and no new machine), got IPv4 onto an IPv6-only network, and cleaned up four routers' worth of config drift.

Fourteen BGP sessions, all FreeBSD, all still fitting on one Grafana screen.

I really don’t need any more peers for my AS201379! (Okay, maybe a few more...)

Started back in December 2025, and now this "little" infrastructure is running:

14 individual eBGP sessions
3 Internet Exchanges
Multiple transit providers
110+ direct peers

All 100% IPv6 (2a06:9801:1c::/48) because legacy IP belongs in the last century.

Powered entirely by FreeBSD : 4 routers on 15.1-RELEASE running FRR and PF.

RE: https://mastodon.bsd.cafe/@grahamperrin/117010090548286954

I use checkrestart after every PKG upgrade.

bastille pkg ALL upgrade
bastille cmd ALL checkrestart

It's nice to surgically restart just the updated processes vs "restart the jail, just to be safe".

#FreeBSD #BastilleBSD

The key to knowing if a FreeBSD box reboot is needed lies in comparing the installed kernel version with the currently running kernel version. How do you do that?

1 Get the version of the running kernel:
`freebsd-version -r`

2 Get installed FreeBSD kernel version:
`freebsd-version -k`

3 Since 14.4-RELEASE-p7 & 14.4-RELEASE-p8 are different versions, reboot it
`sudo reboot`

More here if you want to do this in automated way with ansible https://www.cyberciti.biz/faq/freebsd-determine-if-a-system-reboot-is-necessary/

The terminal screenshot showing FreeBSD commands to check kernel versions and reboot the system by running: freebsd-version -r # <---- Get the version and patch level of the running kernel freebsd-version -k # <---- Get installed FreeBSD kernel version by the freebsd-update command sudo reboot # 14.4-RELEASE-p7 & 14.4-RELEASE-p8 are different versions we need to reboot the system

I converted another host to pkgbase with `pkgbasify`. Worked great!

Even updated the jail base:

./pkgbasify --rootdir /usr/local/bastille/releases/15.1-RELEASE

Bastille even detects that the jail base has been updated, and the next `bastille update 15.1-RELEASE` automatically uses pkg.

The Bastille website has finally been refreshed!

After far too long and far too few updates, the entire website has been redesigned.

Take a look. Let us know what you think.

In this Q2 2026 FreeBSD Journal article, Alice Sowerby looks at the growing role of Software Bills of Materials (SBOMs), why they matter for software security, and what FreeBSD is doing in this area.

You’ll learn:

• How SBOMs help provide greater visibility into software components and dependencies
• How the Cyber Resilience Act (CRA) is changing expectations around software security
• What FreeBSD is doing to support SBOMs

tfw you just regurgitate your LLM slop on a mailing list like it has any value at all https://lists.freebsd.org/archives/freebsd-hackers/2026-July/006651.html

i think we should ban people from the lists for this shit

From the engine room: Today, I updated our entire Mastodon infrastructure for burningboard.net to FreeBSD 15.1-RELEASE-p1 and applied all quarterly package updates. This included the Mastodon App-Server, the opensearch cluster and the Grafana monitoring stack.

Also applied the Mastodon 4.6.4 update and did some cleanup (postgresql repack, removal of orphaned media files, search index rebuild, etc).

All looking perfectly stable and healthy: https://status.burningboard.net :-)
