whio-epfs-label is a tool for getting or setting the label string associated with an EFS container. In addition to the common tools arguments, it supports the following arguments:

  • --label=string or -lstring sets the label to the given string.

Calling it without --label will print the current label to stdout.

The ls tool also lists the label in its output.

An EFS label is solely for client use - the EPFS engine does nothing with it.

The maximum length of a label is defined by the constant value whio_epfs_sizeof_label_payload, defined in whio_epfs.h. The default is "something like 64."
