As part of this change, the OPTIONS may now be a comma-separated

Additionally, the 'blacklist' option in /etc/shorewall/hosts is now

15) The 'blacklist' option in /etc/shorewall/hosts

(/etc/shorewall6/hosts) is now deprecated. It was originally

implemented to handle post kernel-2.6.21 bridges which are now

Setting 'blacklist' in the hosts file is now equivalent to setting

blacklist=1 in the associated entry in the interfaces file.
