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.
Fixes #548
