Subject: [Buildroot] [PATCH 3/5] package/petitboot: poll removable devices
Date: Wed,  6 Sep 2023 14:46:07 -0500	[thread overview]
Message-ID: <20230906194609.74080-4-arbab@linux.ibm.com> (raw)
In-Reply-To: <20230906194609.74080-1-arbab@linux.ibm.com>

Add a udev rule to enable notification of media change events on
removable devices, so petitboot can dynamically adapt to them.
