community/netdata: Netdata fails to create /var/lib/netdata/registry
While attempting to launch netdata on a Raspberry Pi 3B+ (running alpine 3.13.2 aarch64), netdata dies while trying to create the directory /var/lib/netdata/registry. The problem exists on netdata 1.28.0-r0 and 1.29.2-r0. The problem persists whether the path exists or not.
/var is mounted on an ext4 partition on the SD card and is rw.
It seems that mkdir is failing with error code EINVAL. I would expect the error code to indicate a permissions error if that was the cause.
The error.log from one of the netdata runs is attached below. Every run is virtually identical, save for the timestamps and pid.
