Details
The /var/tmp directory is normally a standalone directory in the /var file system. Binding
/var/tmp to /tmp establishes an unbreakable link to /tmp that cannot be removed (even by
the root user). It also allows /var/tmp to inherit the same mount options that /tmp owns,
allowing /var/tmp to be protected in the same manner /tmp is protected. It will also prevent
/var from filling up with temporary files as the contents of /var/tmp will actually reside in
the file system containing /tmp.
*Rationale*
All programs that use /var/tmp and /tmp to read/write temporary files will always be
written to the /tmp file system, preventing a user from running the /var file system out of
space or trying to perform operations that have been blocked in the /tmp filesystem.
Solution
# mount –bind /tmp /var/tmpand edit the /etc/fstab file to contain the following line-/tmp /var/tmp none bind 0 0
