# Set DIFF_ONLY to "1" to only output the difference of the current run

# will output everything that needs to be upgraded.
#

# Set LISTCHANGES_PROFILE if you would like apticron to invoke apt-listchanges
# with the --profile option. You should add a corresponding profile to

# From hostname manpage: "Displays  all FQDNs of the machine. This option
# enumerates all configured network addresses on all configured network inter‐
# faces, and translates them to DNS domain names. Addresses that cannot be
# translated (i.e. because they do not have an appro‐ priate  reverse DNS
# entry) are skipped. Note that different addresses may resolve to the same
# name, therefore the output may contain duplicate entries. Do not make any
# assumptions about the order of the output."
#
# ALL_FQDNS="1"

#
# Set SYSTEM if you would like apticron to use something other than the output
# of "hostname -f" for the system name in the mails it generates. This option
# overrides the ALL_FQDNS above.
#
# SYSTEM="foobar.example.com"

#
# Set IPADDRESSNUM if you would like to configure the maximal number of IP
# addresses apticron displays. The default is to display 1 address of each
# family type (inet, inet6), if available.
#
# IPADDRESSNUM="1"

#
# Set IPADDRESSES to a whitespace separated list of reachable addresses for
# this system. By default, apticron will try to work these out using the
# "ip" command

# Set NOTIFY_HOLDS="0" if you don't want to be notified about new versions of
# packages on hold in your system. The default behavior is downloading and
# listing them as any other package.

#
# Set NOTIFY_NEW="0" if you don't want to be notified about packages which
# are not installed in your system. Yes, it's possible! There are some issues
# related to systems which have mixed stable/unstable sources. In these cases
# apt-get will consider for example that packages with "Priority:
# required"/"Essential: yes" in unstable but not in stable should be installed,
# so they will be listed in dist-upgrade output. Please take a look at
# http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=531002#44
#
# NOTIFY_NEW="0"

#
# Set NOTIFY_NO_UPDATES="0" if you don't want to be notified when there is no
# new versions. Set to 1 could assure you that apticron works well.
#
# NOTIFY_NO_UPDATES="0"

#
# Set CUSTOM_SUBJECT if you want to replace the default subject used in
# the notification e-mails. This may help filtering/sorting client-side e-mail.
# If you want to use internal vars please use single quotes here. Ex:
# \$CUSTOM_SUBJECT='[apticron] \$SYSTEM: \$NUM_PACKAGES package update(s)'

# Set CUSTOM_NO_UPDATES_SUBJECT if you want to replace the default subject used
