The problem is in /sbin/resolvconf
trip any trailing dot from each name as a FQDN does not belong
# in resolv.conf(5)
# If you think otherwise, capture a DNS trace and you'll see libc
# will strip it regardless.
# This also solves setting up duplicate zones in our subscribers.
strip_trailing_dots()
{
local n=
for n; do
printf "%s" "${n%.}"
done
printf "\n"
}
where printf "%s" "${n%.}" is missing space to separate multiple search
values again. Printing additional space at the begining fixed it for me:
strip_trailing_dots()
{
local n=
for n; do
printf " %s" "${n%.}"
done
printf "\n"
}
