Project/Component Working Name: TMPDIR support for Solaris tar 1.2. Name of Document Author/Supplier: Rich.Burridge@oracle.com 4. Technical Description: Summary: This proposal is to modify Solaris tar to honor the environment variable TMPDIR, and to update the man page accordingly. Problem: Currently, tar is hard-coded to create temporary files in /tmp when the "u" operation is performed. Because /tmp is used as the temporary file system for many other commands and operations and as these files can be potentially large, RFE 6719399 is requesting that some method of choosing a directory other than /tmp be provided. Proposed solution: Many utilities and subsystems (vi, pax, sort, cpio, ...) already use the environment variable TMPDIR to select where their temporary files are placed, using /tmp as a default value if that environment variable is not defined. This proposal is to make tar do the same. If TMPDIR is invalid or points to a read-only directory, then tar will default to using /tmp for its temporary directory. Doc impact: The tar manual pages will need to be updated to mention that tar now supports TMPDIR, in the ENVIRONMENT VARIABLES section. Bug 6952051 covers this. The proposed text addition is: TMPDIR tar creates its temporary file in /tmp by default. Otherwise, it uses the directory specified by TMPDIR.

You're the second person to mention this. I just took it from the cpio man page output: $ man cpio ...
