30# It executes in the global zone with the user's identity and
31# basic privileges plus the file_dac_search privilege.  This
32# script should not not assume that stdio is available or that
33# any particular environment variables are set.  In particular,
34# the DISPLAY variable will not normally be pre-set.

36# Authorization checks and zone limit privilege checks
37# are done before calling this script. Auditing is done
