[Pkg-dns-devel] Bug#818930: knot-resolver: trust_anchors.config does not check its argument

[Stephane Bortzmeyer]

Package: knot-resolver
Version: 1.0.0~beta3-1
Severity: normal

Dear Maintainer,

When calling:

trust_anchors.config('/etc/knot-resolver/yeti-root.key')

I discovered that Knot does not check that the file exists. If it
doesn't, there is no error and no warning, but Knot falls back to a
root anchor bootstrapped
