Although Trusted Solaris 8 does not support information labels (ILs), the label_encodings(4) 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: :
INFORMATION LABELS: ... WORDS: ... REQUIRED COMBINATIONS: ... COMBINATION CONSTRAINTS: ...
