Persistent Data Across Flashing

The following data is persistent across flashing:

  1. SSH host keys that uniquely identifies a system during SSH connection setup.
  2. User account metadata files such as /etc/passwd, /etc/shadow, etc. that contains the user's list, user's hashed password, etc.

The exact list of persistent data is located at:

copy_security_data.sh
Note:

Even though user account data is persistent, the user's data itself is not persistent across flashing.
