This depends on how your filesystem is mounted.
We used to directly mount /var to our non-volatile flash partitions but
because of another feature requirement we now mount /var as an overlay
on /tmp:
https://github.com/Intel-BMC/openbmc/blob/intel/meta-openbmc-mods/meta-common/recipes-phosphor/preinit-mounts/preinit-mounts/init#L76
Then we have another service that periodically rsyncs the /tmp overlay
into the non-volatile flash partition to persist the redfish logs:
