File rpi-eeprom-update-Use-tr-instead-of-strings.patch of Package raspberrypi-eeprom
From 462564a95da99016969128dedc6b14ea66b12b17 Mon Sep 17 00:00:00 2001 From: Nicolas Saenz Julienne <nsaenzjulienne@suse.de> Date: Thu, 18 Feb 2021 17:49:46 +0100 Subject: [PATCH] rpi-eeprom-update: Use 'tr' instead of 'strings' The 'strings' utility is installed by binutils whereas 'tr' belongs with coreutils. Minimal systems will only contain the latter, due to binutils' size (20-50 MB). So, convert all uses of 'strings' to 'tr' so as to avoid the package dependency. The second and third 'tr' usage converts non-ASCII characters into newlines so as to isolate the "BUILD_TIMESTAMP=1234567890" statement (similar to what 'strings' does). There is no need for this in the first one: non-ASCII characters are simply discarded as DT aliases have a fixed one line format.
