[Dnsmasq-discuss] Problem with server=/local/127.0.0.1

[Denis]

My configuration:

Manjaro Linux, 32-bit, one ethernet card. It is connected to a router with a cable, the router is connected to my ISP also with a cable. A netbook is connected to the router via Wi-Fi.
On the PC:
Avahi is installed and enabled (avahi-daemon active), 
systemd-resolved is disabled
/etc/resolv.conf is usually filled by NetworkManager, but just before changing dnsmasq.conf and restarting it with different options I manually edited it (/etc/resolv.conf) and left only one line: "nameserver 192.168.1.1" (router address)

Results of "systemctl status dnsmasq.service":

1. With both lines ("local=/local/" and "server=/local/127.0.0.1") commented:
Dec 13 19:32:53 DenDesktop dnsmasq[2564]: dnsmasq: syntax check OK.
Dec 13 19:32:53 DenDesktop systemd[1]: Started A lightweight DHCP and caching DNS server.

Dec 13 19:32:53 DenDesktop dnsmasq[2565]: reading /etc/resolv.conf
Dec 13 19:32:53 DenDesktop dnsmasq[2565]: using nameserver 192.168.1.1#53
Dec 13 19:32:53 DenDesktop dnsmasq[2565]: read /etc/hosts - 5 addresses

2. With only "local=/local/" uncommented:
(1) + one line:
Dec 13 19:48:52 DenDesktop dnsmasq[3122]: using local addresses only for domain local

3. With only "server=/local/127.0.0.1" uncommented:
(1) + one line:
Dec 13 19:38:36 DenDesktop dnsmasq[2788]: ignoring nameserver 127.0.0.1 - local interface

4. With both lines uncommented:
(1) + (2) + (3)

In all these cases my PC's ip address (192.168.1.2) is resolved to my PC's name (DenDesktop). If I "ping DenDesktop.local", the result is:
'PING DenDesktop.local (127.0.0.200) 56(84) bytes of data.
64 bytes from 127.0.0.200 (127.0.0.200): icmp_seq=1 ttl=64 time=0.029 ms'

If I manually insert "nameserver 127.0.0.1" into /etc/resolv.conf above all other nameservers and enable option "strict-order" in dnsmasq.conf, ONLY THEN local names are resolved, i.e. "ping DenDesktop.local" output is:
'PING DenDesktop.local (192.168.1.2) 56(84) bytes of data.
64 bytes from DenDesktop.local (192.168.1.2): icmp_seq=1 ttl=64 time=0.027 ms'

I thought that "server=/local/127.0.0.1" was a functional equivalent of doing exactly that (putting the line "nameserver 127.0.0.1" into the beginning of /etc/resolv.conf): first checked 127.0.0.1 for domain local, then went to /etc/resolv.conf for other nameservers. It seems that the man page says that. So I don't understand why it is not working.
