Are there any files created and or broadened by the system besides mail and logs?
AFAIK, the only files that are created and/or broadened by the system in default are
/var/mail/ files and
/var/log/ files (broadened by means of file size).
To cope with that I've redirected `/dev/null on files in these directories.
But are there more files besides mail and logs that I should worry that they'll be created and broadened by the Linux system itself, throughout time?
