The context mode (single or multiple) is not stored in the configuration file, even though it does
endure reboots. If you need to copy your configuration to another device, set the mode on the new
device to match.

run out of room in that directory, even though there is available memory. In this case, create a
subdirectory for your configuration files. Background: some models, such as the ASA 5585-X, use
