From 9bbe2a8aefe9c840579ba46d0756e71671ac92cd Mon Sep 17 00:00:00 2001 From: Padreug Date: Tue, 26 May 2026 11:52:58 +0200 Subject: [PATCH] =?UTF-8?q?docs(deploy):=20bump=20dd=20count=202200=20?= =?UTF-8?q?=E2=86=92=202800=20for=2025.11=20image=20size?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The 24.05-era image was ~6 GB actual; the README's count=2200 (8.8 GB) gave a small margin. The 25.11 image is 7.3 GB actual (linux-firmware- zstd grew, plus the version churn) — count=2200 would now truncate. Bump to count=2800 (~11.2 GB) and note that future bumps may need another increase — image size is the right thing to check via \`ls -lh result/\`.
