An interesting related point: By default, the current sysinstall doesn't create a separate /tmp. It leaves /tmp as a directory in the rather small root partition. An action as simple as downloading a large file via Lynx (which downloads to /tmp and then moves files to a destination) is enough to overflow the root partition. Has thought been given to changing this? If not, perhaps it should be submitted as a PR. --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
