Although Trusted Solaris 8 4/01 software does not support information labels (ILs), the chk_encodings(1M) command fails with the following error if the label_encodings file omits information about ILs.
# chk_encodings label_encodings Label encodings conversion error at line 37: Can't find INFORMATION LABELS specification. Found instead: "SENSITIVITY LABELS:". label_encodings: label encodings syntax check failed.
Workaround: Copy a valid SENSITIVITY LABELS: section in your label_encodings file, and rename it to INFORMATION LABELS:, as in:
INFORMATION LABELS: ... WORDS: ... REQUIRED COMBINATIONS: ... COMBINATION CONSTRAINTS: ...
