# 'sandbox' enables sandboxing when running emerge and ebuild.
# 'strict' causes portage to react strongly to conditions that are
# potentially dangerous, like missing/incorrect Manifest files.
+# 'userfetch' when portage is run as root, drop privileges to
+# portage:portage during the fetching of package sources.
# 'userpriv' allows portage to drop root privileges while it is compiling,
# as a security measure. As a side effect this can remove
# sandbox access violations for users.
