From 9380347f042f7d294317f4420b648422817eb75a Mon Sep 17 00:00:00 2001 From: Stefan Linke Date: Wed, 7 Sep 2022 17:18:09 +0200 Subject: [PATCH] Avoid warning on grep 3.8 in hwclock Starting with grep version 3.8, the hwclock init script logs warnings about stray backslashes: > hwclock | * Setting system clock using the hardware clock [UTC] ... > hwclock |grep: warning: stray \ before - > hwclock |grep: warning: stray \ before - This is caused by the check for existence of the `--noadjfile` argument in function `get_noadjfile()`. Replacing the affected logic with an explicit argument denoting the pattern as such resolves the issue.
