My guess is that rls-bb-notfixing means this is not getting fixed in
Bionic Beaver 18.04. Really hoping a fix can make it into the 20.04 LTS
release though.
I agree with Paul - systemd-resolve is not doing what it promises to do.
>From systemd.network(5):
Both "search" and "routing-only" domains are used for routing of DNS
queries:
look-ups for host names ending in those domains (hence also single label
names, if
any "search domains" are listed), are routed to the DNS servers configured
for
this interface. The domain routing logic is particularly useful on
multi-homed
hosts with DNS servers serving particular private DNS zones on each
interface.
The "routing-only" domain "~." (the tilde indicating definition of a
routing
domain, the dot referring to the DNS root domain which is the implied
suffix of
all valid DNS names) has special effect. It causes all DNS traffic which
does not
match another configured domain routing entry to be routed to DNS servers
specified for this interface. This setting is useful to prefer a certain
set of
DNS servers if a link on which they are connected is available.
This setting is read by systemd-resolved.service(8). "Search domains"
correspond
to the domain and search entries in resolv.conf(5). Domain name routing has
no
equivalent in the traditional glibc API, which has no concept of domain name
servers limited to a specific link.
One partial workaround is to remove `[!UNAVAIL=return]` after `resolve`
in /etc/nsswitch.conf:
hosts: files mdns4_minimal [NOTFOUND=return] resolve dns myhostname
That way a traditional DNS resolution is done after systemd-resolve
fails. This works for everything I've tested so far _except_ Google
Chrome.
