From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Thu, 30 Apr 2020 15:45:31 +0200 Subject: [PATCH] 10_linux.in: fix early exit due error when reading petitboot version The script uses bash's read built-in command to get the petitboot version version, but this command has a non-zero exit status if the EOF is found. Since the /sys/firmware/devicetree/base/ibm,firmware-versions/petitboot string ends with a NUL character, use the empty string as read delimiter to prevent the command to read to the end-of-file and exit with an error.
