From 35db941bcf30f3fac5b1358aa1124f34f9808950 Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Thu, 2 Apr 2026 07:53:02 +0200 Subject: serial: T8375: add CLI option to explicitly set kernel console Previously, VyOS hardcoded the kernel boot log console to either ttyS0 or tty0, with no post-install CLI method to change it (manual GRUB edits were required). This commit adds a new CLI node: system console device kernel When set, the selected serial console is used as the kernel boot console. When removed, the kernel boot console falls back to tty0. --- src/migration-scripts/system/31-to-32 | 38 +++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 src/migration-scripts/system/31-to-32 (limited to 'src/migration-scripts') diff --git a/src/migration-scripts/system/31-to-32 b/src/migration-scripts/system/31-to-32 new file mode 100644 index 000000000..1688b44ed --- /dev/null +++ b/src/migration-scripts/system/31-to-32 @@ -0,0 +1,38 @@ +# Copyright (C) VyOS Inc. +# +# This library is free software; you can redistribute it and/or +# modify it under the terms of the GNU Lesser General Public +# License as published by the Free Software Foundation; either +# version 2.1 of the License, or (at your option) any later version. +# +# This library is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
