I change it as you say:
dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /dev/sdb1
and i try
option overlay_root /tmp/mountd/disk1_part1
My mount point, usb flash with /overlay is /tmp/mountd/disk1_part1 |18.71 GiB / 19.90 GiB
But have same errors with both variant
root@GL-AX1800:~# opkg list-upgradable
zerotier - 1.8.4-1 - 1.8.4-2
