[c-nsp] What is the file gold_file in bootflash: in a Nexus 3064?

[list-cisco-nsp at jyborn.se]

Hello!

Our rancid came up with this today in a Nexus 3064:
+ !Flash: bootflash:          18    Jan 13 11:45:54 2020  gold_file

I don't think I have seen "gold_file" before, and I can't
find any information about it. I was going to check the
file content, but the file had disappeared.

This is probably some temporary system file that just happened to exist
during this rancid run, but I would like that confirmed if possible.

It is a Nexus3000 C3064PQ Chassis running NXOS: version 7.0(3)I7(6) on BIOS: version 4.5.0.

Thanks!

Peter
