Error message

not implemented

What it means

Error "not implemented" thrown in uutils/coreutils.

Solutions

1. This filesystem operation is not implemented for the current platform; use a supported OS or an alternative API.
2. Gate the calling code with cfg so the unsupported path is not reached.

When it happens

Trigger: Occurs when a filesystem extended-attribute or mount-info operation in fsext is called on a platform where it is not implemented.

Common situations: Querying mount or filesystem metadata on targets lacking the underlying OS API used by fsext.
