Author: eugen Date: Sat Nov 10 14:21:26 2018 New Revision: 340322 URL: https://svnweb.freebsd.org/changeset/base/340322 Log: Prevent periodic/etc/weekly/340.noid from descending into root directories of jails. Jails have their own user/group databases and this script can produce multiple false warnings, not to mention significant extra load in case of large jailed subtrees. Leave this check for jailed invocations of the same script.
