n The system variable USER_PARTITION is a system variable organized as a data
structure.
n You can use the USER_PARTITION system variable to retrieve various information
and memory statistics on the user partition (overlay file system).
n The partition can be on the external Yaskawa SD card or on the internal memory.
n The memory is organized in blocks.
n A block has a constant, fixed size and a file always uses one or more blocks.
n A certain number of blocks are reserved in the Linux system for the root user. These
reserved blocks are only available for the root user and ensure his ability to act even
if the memory is occupied (e.g. for log outputs).
