butrelinux  

a bluefin-lts variant for those who want EL10+KDE

local package layering is disabled by default. you can change this with the command below, though the intended workflow is distrobox + flatpaks.

sudo givemethekeys unlock

Usage: givemethekeys <command> [options]

Commands:
  unlock    Allow rpm-ostree package layering
  lock      Restore default layering lock
  status    Show current layering lock status
  help      Show this help

Options:
  -y, --yes    Skip confirmation prompt (unlock only)

the ISO is the main installation path, rebase instructions are provided for convenience for existing bluefin lts users.

installation

ISO downloads available here:

rebase instructions

if you use the rebase instructions you must rebase from a centos stream derived image such as bluefin-lts, not any fedora version. this image is based on centos stream 10, not fedora, and cross-rebasing will break things.

Warning

This is an experimental feature, try at your own discretion.

to rebase an existing EL10 based installation to the latest build:

amd/intel

# optionally clean up default flatpaks
flatpak uninstall --all
# rebase to the unsigned image, to get the proper signing keys and policies installed:
rpm-ostree rebase --reboot ostree-unverified-registry:ghcr.io/butrejp/butrelinux-hwe:latest

after the system reboots:

# since skel can't touch existing users, optionally copy the default configs to your user profile
# or just make your own config.  I'm not your mom.
mkdir -p ~/.config && cp -r /etc/skel/.config/* ~/.config/
# rebase to the signed image to complete the installation
rpm-ostree rebase --reboot ostree-image-signed:docker://ghcr.io/butrejp/butrelinux-hwe:latest

nvidia

flatpak uninstall --all
rpm-ostree rebase --reboot ostree-unverified-registry:ghcr.io/butrejp/butrelinux-nvidia:latest

after the system reboots:

mkdir -p ~/.config && cp -r /etc/skel/.config/* ~/.config/
rpm-ostree rebase --reboot ostree-image-signed:docker://ghcr.io/butrejp/butrelinux-nvidia:latest

alternatively, there's butrelinux-lts or just butrelinux (legacy GDX image). if you're not sure whether you should install these two, you probably shouldn't.

verification

these images are signed with sigstore's cosign. you can verify the signature by downloading the cosign.pub file from this repo and running the following command:

cosign verify --key cosign.pub ghcr.io/butrejp/butrelinux

if you ever hit ASN.1 invalid signature failure during an upgrade it's because I rotated out the keys. sorry. it was probably dependabot's fault. you can fetch the new keys with the following command

sudo curl -Lo /etc/pki/containers/butrelinux.pub https://raw.githubusercontent.com/butrejp/butrelinux/refs/heads/main/cosign.pub

news

20260608 release

20260608
I think this can be considered the first true stable release. I don't expect to shift things around too much at this stage.
the only inclusion left that I don't really like is gearlever and I'm investigating alternatives but unfortunately that one gtk app happens to be the one that works the best. maybe someday appimagelauncher will be the go to, but not until the next major release at earliest.

distrowatch

20260610
hey I've got a distrowatch page now. no idea who submitted it but that's pretty cool.
visibility wasn't really the intent, I just wanted something that fit my tastes that I didn't have to remove anything from, only needing to add to it depending on the deployment. I suppose it's distributed, and that makes it a distro.

cosign keys updated

20260520
run sudo curl -Lo /etc/pki/containers/butrelinux.pub https://raw.githubusercontent.com/butrejp/butrelinux/refs/heads/main/cosign.pub to get everything sorted again without having to reinstall
a new iso will be published shortly (done)

big reorganization

20260708
https://docs.projectbluefin.io/blog/2026/07/02/organizational-migration-for-bluefin-lts-gdx/
bluefin is reorganizing and the old bluefin-gdx is getting discontinued, meaning my previous upstream is getting discontinued. the standard gdx:lts image is staying and will keep building if you want to keep using it, but all work is moving towards the new images, so the day butrelinux:latest stops building is the day it's done. butrelinux-hwe and butrelinux-nvidia is the new hotness. new isos will hopefully be built this week. just bootc switch or rpm-ostree rebase in the mean time if you want to try it, but for now I recommend sticking with the old version, as new just isn't stable yet.
also, I decided to use this as an opportunity to break out a standard installation and an nvidia installation. have fun with that amd users

Warning

This is an alpha release. when upstream stabilizes, I'll stabilize.

20260714 UPDATE
ISOs are out. have at it.
also got a unified iso in the works but matrix builds are easy so split installers came first

20260715 UPDATE
unified iso was easier than I thought. they've been available since yesterday. still tweaking, so expect fresh releases to come regularly, but installer behavior shouldn't change much. once I get it all sorted out it'll be monthly builds pushed automatically
