Yet another reason to use etckeeper to version /etc automatically unless
you're using a snapshotting filesystem or something similar.
/etc/hosts is provided by the debian-installer netcfg package and as
such *shouldn't* be touched by post-install packages so it's unlikely
you missed one of the messages that go like this:
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
So you can grep for it but I doubt there will be an /etc/hosts.dpkg-old
as it won't be apt that's clobbered it.
Version or snapshot any mountpoint you care about I guess is the moral
of the story. At least it was only hosts eh, and not sshd_config...
Cheers
