This can result removal of files that haven't really occuplied space on the system as long as file timestamps indicate. Sensibility aside, this may cause very adverse effects if, for instance, a NFS file system is mounted under temporary directory even for a moment, and cleanup scripts comes around. >How-To-Repeat: Create files with old enough timestamps under a test file system, mount it under filesystem to be cleaned, and run /etc/periodic/daily/110.clean-tmps. >Fix: Documentation of find -x option is a bit obscure. Is it intended for this purpose? Another option is -fstype local, but that doesn't work on diskless systems as intended. >Release-Note: >Audit-Trail: >Unformatted:
