Using pkg to update both base and ports with a single tool will be nice. As will updating jails robustly; freebsd-update is not so great in jails in my experience.

freebsd-update works fine in jails, as long as you use it correctly. Unfortunately there are a few landmines due to versioning issues.

".. use it correctly": As in excluding the kernel component in freebsd-update.conf or how do you mean?

Honest question: what is the big deal about syspatch? I see OpenBSD folks talk about it as if it is the greatest thing since sliced bread. How is this different from what many distributions have had for more than a decade in the form of apt or yum?

Can't use Linux distribution tools like apt/yum unless you package the update contents as rpm/dpkg files and distribute apt/yum with the base system. Neither of those is happening in OpenBSD, or likely any BSD. (I can go into more detail on why if you're curious.) In some ways, the BSDs are just catching up to Linux in terms of update distribution mechanism. They all have a history of being self-hosting compile-from-…

Packaged base is a beta feature in FreeBSD https://wiki.freebsd.org/PkgBase But IMO there's nothing wrong with freebsd-update.

Yeah, I'm familiar — I'm a FreeBSD developer. Pkgbase is a feature in development; it's not officially complete or supported in any release.

In this case it's just about sane defaults and options. You could take any binary-update Linux distribution and update from source yourself if you wanted to. It was always an option. All of the build machinery and sources were published from the beginning.

With the BSDs, you didn't even have the option of binary updates or packages until quite recently.

Yes, but like Debian, OpenBSD is ignoring that. Fedora, openSUSE, Mageia, etc. use the official term. Debian and the BSDs use the informal "arm64" term.

The informal makes more sense, BTW.

True, but there's some merit to being consistent with the naming used by the toolchain (which appears in things like cross compiler binary names) and the name printed by the linux kernel in 'uname -a')...

Just glancing at the man page, atomic rollback kinda jumps out...

Is that the same as using yum history to roll back?

The place people usually trip up is with freebsd-update getting confused about what version it's trying to update. The '--currently-running ' option is your friend here.

so does this mean smart phones and IOTs can run on BSD?

OpenBSD support list [0] at the moment:

> The current target platforms are Rockchip RK3399, Allwinner A64/H5, Raspberry Pi 3 and Opteron A1100.

That's a good list, it may cover a number of "Maker"-oriented single-board computers that are fun to play with.

Note that most of the Raspberry Pi chip is its Broadcom Videocore IV graphics processor, which is not supported by the OpenBSD OS. You would have to hook up a screen to the GPIO pins, I think, rather than getting display out of the HDMI port. There are lots of LCD display "hats" on the market.

(I am typing this on my iPad, which is an iOS device, which is a descendent of BSD.)

You can use an RS232/USB connector to hook it up to a VT100-compatible terminal or emulator. That’s what I plan to do this afternoon.

Alternatively you can just SSH 59 it. It depends on what your objectives are.
