[Bug 2107308] [NEW] Referenced but unset environment variable evaluates to an empty string

[Sundar Nagarajan]

Public bug reported:

Warning (not error) appears in journalctl log

cron.service: Referenced but unset environment variable evaluates to an
empty string: EXTRA_OPTS

Reason:

/etc/default/cron contains:

# This file has been deprecated. Please add custom options for cron using
# $ systemctl edit cron.service
# or
# $ systemctl edit --full cron.service


With no reference to EXTRA_OPTS


Fix:
Add one line to /etc/default/cron setting EXTRA_OPTS to empty string:

# This file has been deprecated. Please add custom options for cron using
# $ systemctl edit cron.service
# or
# $ systemctl edit --full cron.service
EXTRA_OPTS=""
