My guess is that the problem is InsertLine. Are you using it within a
BeginGroup/EndGroup contruct? The manual says: "This should probably be
used in conjunction with the conditional begin-end tests to avoid lines
being inserted on every run," but I think it means "must" rather than
"should."
I would do:
{ /etc/hosts
DeleteLinesContaining "${host}"
AppendIfNoSuchLine "127.0.0.1 ${host}"
}
That should work. In won't update the file unless the edited buffer
differs from the on-disk copy, so despite the fact that I am using
a delete command, most of the time if won't get edited.
If you give us the exact editfiles stanza you are using, we can make
other suggestions.
