+ SafeSetID is an LSM module that gates the setid family of syscalls to
+ restrict UID/GID transitions from a given UID/GID to only those
+ approved by a system-wide whitelist. These restrictions also prohibit
+ the given UIDs/GIDs from obtaining auxiliary privileges associated
+ with CAP_SET{U/G}ID, such as allowing a user to set up user namespace
+ UID mappings.

+ If you are unsure how to answer this question, answer N.
