Mode "import_non_settable" enables obtaining of non\-settable attributes from

all attribute flags are zero.
.br
Mode "import_only_settable" causes non\-settable attributes ("eEhINVZ") to be
ignored when file objects get read from disk. If the remaining attribute flags
are all zero, then no attribute information gets attached to the file in the
ISO. This saves storage and eases finding of non\-trivial attributes in the
ISO image.

Mode "restore_error=" sets the behavior for the event that restoring of
attribute flags to the local filesystem fails. Available are the
keyword "silent" and the severities from "all" to "fatal".
"silent" and severity "all" suppress any error messages and abort
considerations caused by restore attemps of attribute flags. Else the error
message is issued with the given severity. Then it depends on the setting
of command \-abort_on whether restoring goes on or gets aborted.
