dustin/metricspi/pipeline/head This commit looks goodDetails
By default, Buildroot creates `/etc/resolv.conf` as a symlink to
`/tmp/resolv.conf`. This allows it to be modified at runtime, even if
`/` is on a read-only filesystem (assuming `/tmp` is not).
Unfortunately, this causes problems for systemd units with
`PrivateTmp=yes`, because they are not able to read the `resolv.conf`
file.
A more appropriate location for the writable `resolv.conf` is `/run`.
This filesystem is not affected by the `PrivateTmp` setting, and is
always available to units.
