> Flashed 19.07.06 via the sysupgrade process, keeping the existing configuration. After installation, the dnsmasq Resolve file setting was left with the following invalid path:
Sounds like you have downgraded from a master snapshot to 19.07.6.
That downgrade path is nto supported for dnsmasq.
The resolv directory in dnsmasq config was changed a year ago in January 2020 by dangowrt with commit cd48d8d342:
The broke also master configs in sysupgrade, so a migration was provided two days later by 6a2855212:
Those commits effectively block downgrading from master to 19.07 unless you adjust the dnsmasq config to the dnsmasq 19.07 expectations.
I guess that this bug will end up with WONTFIX, as downgrading from a year 2020 or 2021 master build to a 19.07.x build (mainly with year 2019 code) is not really in focus.
I include a config migration script in my own 19.07 builds, so that 6a2855212 gets applied reverted when you move from master to 19.07.
