[Pkg-utopia-maintainers] Bug#948681: firewalld: Nukes the existing network system without warning

[Brad Rigby]

Source: firewalld
Severity: normal

Dear Maintainer,

The debian wiki notes that debian is moving from iptables to nftables, and the nftables page suggests installing this package.  So I did.  Unfortunately, I did so via an ssh connection, as the computer in question is a headless router.  As soon as aptitude quit I was booted from the system.  I therefore needed to find a keyboard and monitor, and cables, to hook up to this somewhat antiquated system in order to fix the problem.

Please give a warning somewhere that before installing, a person should have physical access to the machine.  Even better would be a debconf wrapper to allow configuration before the default completely nukes everything.
