Subject: [Buildroot] [PATCH 2/5] package/petitboot: run pb-console at boot
Date: Wed,  6 Sep 2023 14:46:06 -0500	[thread overview]
Message-ID: <20230906194609.74080-3-arbab@linux.ibm.com> (raw)
In-Reply-To: <20230906194609.74080-1-arbab@linux.ibm.com>

Install a udev rule to run the petitboot UI on commonly-known consoles.
To prevent the kernel's console output from trampling the UI, also add
a sysctl file to reduce the kernel log levels to KERN_ALERT.
