utils: T8541: add write-config-file-value helper

2026-04-26T17:38:17+00:00

Introduce src/helpers/write-config-file-value.py to patch a saved config.boot from scripts by writing a quoted CLI path with an optional value (omit --value to create a valueless node). Extend vyos.utils.config.write_saved_value() to safely update saved configs: create missing parent nodes before tagging (ConfigTree.set_tag requires nodes to exist) and then write the requested value/valueless leaf back to disk. Remove the legacy serial console activation script which is now replaced by the helper-based approach. The helper is run once during ISO Image assembly and will inject the approprate serial console defintiions into config.boot.default.

serial: T8375: add CLI option to explicitly set kernel console

2026-04-09T18:54:06+00:00

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.

serial: T8375: use boot activation script to define a serial console on the CLI

2026-04-09T18:54:06+00:00

Required during first-boot of a system. We have images form amd64 and arm64 CPUs which also tend to have different serial interfaces (ttyS vs. ttyAMA). The images which are installed have the correct serial setting for GRUB (ttyS0 or ttyAMA0) and the activation script will probe the Kernel command-line. If a serial interface is defined, we will include it in the VyOS CLI configuration.
