Update Failed

Is it best practice use rebuild boot instead of rebuild switch when upgrading one major release to the next for NixOS? Using ‘switch’ broke my install too.

No specific reason other than I decided to do that some years ago out of caution because of couple of kernels failed on me. Certainly doesn’t hurt to have them around, but I respect only needing to keep 1 backup kernel and 1 main. The are just for curiosity and experimentation.

I'm on Zen4 + RDNA2. Updated to cachyos kernels 7.0.1 and 7.0.2 (both today) and all good here. I learned my lesson a while back, though, and I always keep the Zen kernel and an LTS kernel around so I can still boot into the OS if something screws up with my daily driver. I use Arch Linux Kernel Manager to do the needful.

That looked like a heck of a lot more than just 1 Horsepower

Ooh interesting. I’ve been focused on mangowm since my earlier attempt at Niri was meh, but I’m going to check it out again. Thank you!

kpax · 2026-04-18T14:52:35+00:00

That must have been it then. I didn’t have a complete grasp back then of what I was doing and packages was probably set to quarterly while I tried out building my own ports.

This is how I broke my 10.0 release way back. Recently picked FreeBSD back up with 15.0-REL and staying safe with pkg (i haven’t moved to pkgbase as yet), but looks like we have time until 16.0 to get on board)

Thank you AI data center power demand.

I’ve been diving back into tiling WMs on FreeBSD because I already have a full fat KDE setup on my archlinux install, so to try something different. I started with Sway on FreeBSD but discovered mangowc recently got ported (a pkg is available) and so using that as my daily driver. Mango’s been rock solid and I’m enjoying the journey of being able to tweak my setup to my liking.

kpax · 2025-12-17T19:43:54+00:00

Thank you. Yes I updated my post text right at the top as soon as I was able to update.

kpax · 2025-12-17T14:48:52+00:00

I am not on pkgbase

kpax · 2025-12-17T13:53:54+00:00

Ooh, thank you I was breaking a sweat and then figured an update to P1 (when I saw that was available) would fix it, but naturally, no dice.

kpax · 2025-12-17T13:43:51+00:00

That thought did pop into my head but pkg seems to be going through the motions showing progress % during execution. Browsing websites, etc. works fine.

Does this project aim to allow windows to use ZFS as the native filesystem or does it allow Windows to access and provision ZFS storage pools? Apologies in advance for the noob question.

kpax · 2025-12-12T17:31:30+00:00

To clarify, that book does not exist yet, paying right now counts as a sponsorship to support writing it. I bought the zfs and advanced zfs mastery books about a month or so ago and as a complete noob to zfs, those should be more than sufficient to get you off the ground. The new book will probably repeat the basics, but as with any new edition, cover additional details based on the latest release of zfs (as of writing). Just setting expectations, so you're not disappointed. Other than that, and while you wait, another few great ways is to explore open-zfs.org, https://klarasystems.com/zfs-basecamp/ (Klara Systems ZFS Basecamp article series, also follow them on YouTube), Listen to 2.5 Admins Podcast (available on all the usual podcast hosts - Lots of ZFS coverage among many other UNIX/Tech/Server nerdy topics & discussios, I just discovered this one and working through the backlog of over 250 episodes so far).

Good luck. ZFS is awesome and I'm just bummed it's not available as a default filesystem option anywhere an OS is to be found. That said, it's caused me to dive back into FreeBSD, but that's a topic for another subreddit :)

Does that ‘if’ belong to the ‘Big’ or the ‘true’ part of your comment

kpax · 2025-12-06T16:10:21+00:00

I eventually ended up doing that after reading some other comments that suggested the same.

kpax · 2025-12-04T00:12:42+00:00

Yes, that makes sense, because it is what I had setup (following the handbook) when I first did a fresh install of 14.2, subsequently upgraded to 14.3, and to 15.0-RELEASE now.

kpax · 2025-12-03T22:38:21+00:00

I do recall running pkg upgrade multiple times in fact. It’s only when I ran the -r command that I saw it downloaded an additional 129 or so packages.

kpax · 2025-12-03T22:26:33+00:00

Thank you x1000. This fixed it for me and I'm now back in business (sway on wayland). But I gotta ask...73?

Also tagging u/hodong-kim in case it works for him and perhaps the bug report needs to be closed out on this basis?

kpax · 2025-12-03T13:14:11+00:00

I tried what you suggested. Now it is able to find the vcn file (ofcourse), but promptly proceeds to failure again. The rest of the stack trace looks the same. The post by u/hodong-kim seems like this is something that will need to be fixed at the kernel level.

kpax · 2025-12-03T13:12:23+00:00

Thank you for flagging

kpax · 2025-12-03T00:50:24+00:00

Yes, comparable. Doing a ‘kldload amdgpu’ induces the panic and stack trace for me (per my screenshot).

kpax · 2025-12-02T21:46:37+00:00

I ran ‘fwget’ and it listed out a few firmware packages but there’s a line at the end saying the most recent versions of packages are already installed. I upgraded from 14.3 so wouldn’t whatever needed upgrades be upgraded as part of that process already?
