* [PATCH] installer: suppress kernel info/debug messages @ 2025-12-23 2:15 'Badrikesh Prusty' via isar-users 2026-01-05 9:24 ` Anton Mikanovich 0 siblings, 1 reply; 9+ messages in thread From: 'Badrikesh Prusty' via isar-users @ 2025-12-23 2:15 UTC (permalink / raw) To: isar-users; +Cc: florian.bezdeka, Badrikesh Prusty Lower the kernel log level to 4 to suppress notice, info, and debug messages on the console. This prevents audit and driver messages from cluttering the screen while keeping critical errors and systemd service status output visible, resulting in a cleaner installer UI.

This has already been addressed by changing the log level from loglevel=3 to loglevel=4 in v2 of the patch. With loglevel=4, warning messages are displayed, and only info and debug messages are skipped.

Prusty mentioned "... resulting in a cleaner installer UI.", so I was assuming he is concerned about the installer / target-bootstrapper output. If so reducing/limiting kernel logs from the execution of the target- bootstrapper service (and yes that's a systemd service) onwards should be sufficient for the specific case, while preserving default logs during boot. Else, if not, and the kernel log itself is for some reason too cluttered for audit aso., then why should it only be appled to the installer image and not in general? > > > > > > > > > > > OVERRIDES .= "${@':unattended-installer' if > > > > bb.utils.to_boolean(d.getVar('INSTALLER_UNATTENDED')) else ''}" > > > > ADDITIONAL_KERNEL_CMDLINE:append:unattended-installer = " \ > > > > -- Alexander Heinisch Siemens AG www.siemens.com -- You received this message because you are subscribed to the Google Groups "isar-users" group.
