It doesn't: the path is a compile-time parameter. It's not clear that the entities on the other end of the UBus under openwrt could cope with multiple instances. The pragmatic solution might be to turn Ubus off for one of them.

Re: [Dnsmasq-discuss] ubus problem
@Jan? (I suspect that nothing has changed, except that a previously silent error is now no longer silent, but it would be nice to confirm this, and maybe explicitly consider this case.)

[Dnsmasq-discuss] ubus problem
Hi, I'm using the latest dnsmasq version with openwrt. There are two instances running. One provides dhcpv4, dhcpv6 and dns to several networks, the other one dhcpv4 to one network only. It looks like, that the second instance has a problem with ubus: Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: Connected to system UBus Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: started, version 2.80-52-ga2b8220 cachesize 300 Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: compile time options: IPv6 GNU-getopt no-DBus UBus no-i18n no-IDN DHCP DHCPv6 no-Lua no-TFTP no-conntrack no-ipset auth DNSSEC no-ID loop-detect inotify dumpfile Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: UBus support enabled: connected to system bus Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: DNSSEC validation enabled Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: DNSSEC signature timestamps not checked until receipt of SIGINT Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: configured with trust anchor for keytag 20326 Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: configured with trust anchor for keytag 19036 Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using only locally-known addresses for domain test Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using only locally-known addresses for domain onion Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using only locally-known addresses for domain localhost Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using only locally-known addresses for domain local Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using only locally-known addresses for domain invalid Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using only locally-known addresses for domain bind Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using nameserver 2a02:::::::#53 Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using nameserver 46.zzz.zzz.zzz#53 Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using nameserver 2a03:::::::#53 Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using nameserver 146.zzz.zzz.zzz#53 Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: using only locally-known addresses for domain lan Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: read /etc/hosts - 4 addresses Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1808]: read /tmp/hosts/dhcp.main - 29 addresses Sun Apr 7 18:37:34 2019 daemon.err dnsmasq[1809]: Cannot add object to UBus: Invalid argument Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1809]: started, version 2.80-52-ga2b8220 DNS disabled Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1809]: compile time options: IPv6 GNU-getopt no-DBus UBus no-i18n no-IDN DHCP DHCPv6 no-Lua no-TFTP no-conntrack no-ipset auth DNSSEC no-ID loop-detect inotify dumpfile Sun Apr 7 18:37:34 2019 daemon.info dnsmasq[1809]: UBus support enabled: bus connection pending >From the first I see: daemon.info dnsmasq[1808]: Connected to system UBus daemon.info dnsmasq[1808]: UBus support enabled: connected to system bus >From the second I see: daemon.err dnsmasq[1809]: Cannot add object to UBus: Invalid argument daemon.info dnsmasq[1809]: UBus support enabled: bus connection pending Sometimes, the starting sequence is inverted.
