[ bug ] FreeBSD OS line is incorrect

[yonas]

Currently, the OS and Kernel report the same patch level, which is the kernel patch level.

Using sysctl -n kern.osrelease does not provide the correct information. The OS line should report p3 as per freebsd-version -u.

Can we switch to running freebsd-version -u for the OS line?

Reference:

libmacchina/src/freebsd/mod.rs

Line 91 in df86ae6

os_release_ctl: Ctl::new("kern.osrelease").ok(),

[grtcdr]

Is there some other kernel parameter we can query to retrieve that information? I'd rather we used Ctl which as far as I remember does not involve launching an external process to retrieve OS information.

@grtcdr Not currently:

$ sysctl -a | grep '\-p\d+'
kern.osrelease: 14.2-RELEASE-p1
kern.version: FreeBSD 14.2-RELEASE-p1 GENERIC

[yonas]

To be honest, I feel like the behavor of sysctl -n kern.osrelease must be a bug, otherwise we'd have duplicate parameters with kern.version.

I'll send an email to the freebsd-hackers mailing list.

Edit: I suspect they'll say sysctl is kernel related, so it wouldn't appropriate to have non-kernel values there. That makes sense, so I'll hold off on the email for now.

freebsd-version -u reports the hardcoded userland version, while freebsd-version -k reports the running kernel version. I suspect in 14.2-RELEASE-p2 and 14.2-RELEASE-p3 the kernel code was not changed, hence the difference.

Fastfetch acquires the userland version from /etc/os-release, just like what Linux distros do.

Oh cool, guess we could use that then, thanks for the info!
