｢debootstrap --variant=buildd｣ → no /etc/hosts either.

This said, your fix works for now, a better one is a matter for the
upstream.  And as libexplain seems to be dead upstream, despite it being a
nifty concept, no one is likely to use it in new project, meaning the issue
will fix itself.

It cannot even be reproduced in the sid buildd chroots,
only with "debootstrap --variant=minbase" - fixing in
jessie or stretch is therefore not required.

At a quick glance the look_for_similar() functionality in
libexplain/buffer/errno/path_resolution.c cannot be disabled, therefore
a proper solution for making the test output deterministic (independent
of the content of /etc) is not easily possible. The tests also don't
seem to support regular expressions ...

I'd suggest to add the B-D: netbase, and reconsider this decision once
base-files ships /etc/hostile in case that is a better suggestion than
/etc/hosts :-)

Can this bug be reproduced in stretch or jessie buildd chroots - or can
we tag it sid+buster?

Not sure if this is the best way to fix the failure, although it _would_
make the error message find /etc/hosts there so it can be suggested.

This test is fragile, though -- if you have a file named /etc/hosting or
such, it'll be picked instead of "hosts".

The root cause, though, is that libexplain knows about gethostid, thus it
can rule out an user making a typo -- the function looks for /etc/hostid and
hothing else.
