Core with slot C enabled
Follow the four steps above. Maintenance and confirmation are automatic. Later R1 signed updates use this same process.
BRIMSTONE CORE R1 · 1.0.0-rc.2 · 4 NOVEMBER 2026
The R1 release candidate brings together the current listening, metadata and Meridian fixes. Install the signed update through Core’s existing update screen. Your music and library stay where they are.
Release candidate · planned 1.0.0 launch: 14 November 2026. Final release remains subject to the remaining checks.
FOR CORE WITH THE SLOT-C UPDATER INSTALLED
The new R1 installer includes the trusted slot-C updater. Existing installations may have it from a separate support setup. The updater decides the route; you do not need to choose a boot slot yourself.
Finish playback, ripping, recording, imports and downloads. Leave Core connected to power.
Open Settings → Updates & Recovery. Upload the complete signed .tar.gz archive without extracting it. Check the verified version is 1.0.0-rc.2, then choose Activate.
Core makes its database backup, boots maintenance slot C, updates the inactive system slot and boots back into the new Core. Allow both restarts to finish.
Refresh the Core page. Check the installed version, open an album and try your usual speaker. A healthy exact-version boot is confirmed automatically. Your previous system slot remains available for rollback.
WHICH CORE ARE YOU UPDATING?
A version number alone does not tell you which privileged updater has been installed. An ordinary application archive cannot silently replace that trusted component.
Follow the four steps above. Maintenance and confirmation are automatic. Later R1 signed updates use this same process.
Upload the same signed update in Settings and follow the route your installed helper offers. It stages the inactive A/B application. After restarting and checking playback, use Confirm update if shown.
The application patch preserves that earlier helper; it does not add C automatically. Contact support for the separate one-time C setup.
Use the administrator-console instructions below for the first update. A modified or unknown installation must be reviewed rather than forced through.
First-update instructions ↗A container has no independent A/B/C boot slots. Use its managed application update or administrator-supported native-service update. Do not run the disk installer or A/B patch command inside LXC.
WHAT R1 1.0.0-rc.2 INCLUDES
Core-first album selection, improved lyric timing and DruidCast podcast queues through supported native Meridian receivers. MS200 listening has been confirmed; other physical models retain their individual acceptance requirements.
Enhanced album and artist information, artwork, credits, booklets and manual corrections remain part of the current baseline. Updating does not rebuild your collection from scratch.
Core, the signed update and the new installer use 1.0.0-rc.2. 1.0.0 is reserved for the planned R1 launch.
Download the update and its matching checksum into a folder on persistent DATA. Verify the checksum before extracting or running it. These commands are for a normally booted full Core A/B system, not LXC or manually selected recovery C.

sudo python3 apply_patch.py --check
sudo python3 apply_patch.py --apply --activate
sudo rebootAfter a healthy boot, return to the same directory on DATA and run sudo python3 apply_patch.py --confirm. This route adds the earlier trusted A/B web helper. Separate C setup is still required.
If validation refuses the signature, baseline, layout or database, stop and send the error to support. Do not change the checks or select another disk.
Refresh the update status and read the saved result. Do not repeatedly upload or restart while an operation is in progress. The new C updater confirms the exact healthy release or selects the previous system slot if the new Core fails its startup check.
Use Roll back application in the update screen if needed. Application rollback retains current DATA; it does not rewind your library or media.
The new 1.0.0-rc.2 ISO is built with the C updater and has passed image-integrity checks. Fresh BIOS/UEFI boot and installation qualification is still pending, so its download is held. The existing tested installer remains on the installation page.
