COMPATIBILITY WITH RESOLVCONF(8)
resolvectl is a multi-call binary. When invoked as "resolvconf"
(generally achieved by means of a symbolic link of this name to
the resolvectl binary) it is run in a limited resolvconf(8)
compatibility mode. It accepts mostly the same arguments and
pushes all data into systemd-resolved.service(8), similar to how
dns and domain commands operate. Note that
systemd-resolved.service is the only supported backend, which is
different from other implementations of this command.
/etc/resolv.conf will only be updated with servers added with
this command when /etc/resolv.conf is a symlink to
/run/systemd/resolve/resolv.conf, and not a static file. See the
discussion of /etc/resolv.conf handling in
systemd-resolved.service(8).
Not all operations supported by other implementations are
supported natively. Specifically:
-a
Registers per-interface DNS configuration data with
systemd-resolved. Expects a network interface name as only
command line argument. Reads resolv.conf(5)-compatible DNS
configuration data from its standard input. Relevant fields
are "nameserver" and "domain"/"search". This command is
mostly identical to invoking resolvectl with a combination of
dns and domain commands.
-d
Unregisters per-interface DNS configuration data with
systemd-resolved. This command is mostly identical to
invoking resolvectl revert.
-f
When specified -a and -d will not complain about missing
network interfaces and will silently execute no operation in
that case.
-x
This switch for "exclusive" operation is supported only
partially. It is mapped to an additional configured search
domain of "~." — i.e. ensures that DNS traffic is preferably
routed to the DNS servers on this interface, unless there are
other, more specific domains configured on other interfaces.
-m, -p
These switches are not supported and are silently ignored.
-u, -I, -i, -l, -R, -r, -v, -V, --enable-updates,
--disable-updates, --are-updates-enabled
These switches are not supported and the command will fail if
used.
See resolvconf(8) for details on those command line options.
