1. In the following example, USB volume Samsung 2GB is mounted but not shared. The network path ‘WORKGROUP/GL-Samba’ is visible in network browser on client devices, but no shared volume appears when file sharing is enabled in the GUI at http://{router IP}/#/share.
OpenWrt 18.06.1, r7258-5eb055306f

3. Request support for Avahi / Zeroconf
“OpenWrt offers several different packages supporting the different zeroconf implementations.” (But none are available in the GL.inet repository)
Avahi (Linux) - avahi-daemon-service-ssh, avahi-daemon-service-http, avahi-utils, avahi-autoipd, avahi-dnsconfd
Bonjour (Apple) - mdnsresponder, mdnsd
umdns (OpenWrt own package)
Zeroconf/UPnP SSDP (Microsoft, incompatible with mDNS)
