The per-user configuration file lives in `$HOME/.resinrc.yml` or `%UserProfile%\_resinrc.yml`, in Unix based operating systems and Windows respectively.
The Resin CLI also attempts to read a `resinrc.yml` file in the current directory, which takes precedence over the per-user configuration file.
Alternatively, you can edit your configuration file and set `resinUrl: resinstaging.io` to persist this setting.
### How do I make the Resin CLI persist data in another directory?
The Resin CLI persists your session token, as well as cached images in `$HOME/.resin` or `%UserProfile%\_resin`.
Pointing the Resin CLI to persist data in another location is necessary in certain environments, like a server, where there is no home directory, or a device running Resin OS, which erases all data after a restart.
You can accomplish this by setting `RESINRC_DATA_DIRECTORY=/opt/resin` or adding `dataDirectory: /opt/resin` to your configuration file, replacing `/opt/resin` with your desired directory.
### Why do I get `Invalid MBR boot signature` when configuring a device?
This error, accompanied with something like: `Expected 0xAA55, but saw 0x29FE` usually indicates a corrupted device operating system image in the cache, due to bad a internet connection during the download process.
Try clearing the cache with the following command and trying again:
