>Description:
pax does not respect TMPDIR.  environ(7) says:

     TMPDIR     The directory in which to store temporary files.  Most appli-
                cations use either /tmp or /var/tmp.  Setting this variable
                will make them use another directory.

However, pax ignores the setting of TMPDIR and throws its temporary
files into /tmp.  This means that if, for whatever reason (e.g.
no inodes left in /, as seems to be the case in the arm32 1.4
distribution disk image!) you can't write to /tmp, you can't use pax
to extract files.
>How-To-Repeat:
arrange for /tmp to be unwritable, try to extract files with
pax.

alternately, look at the pax source.
>Fix:
make pax respect TMPDIR.  (while at it, probably a good
idea to make it not hard-code the /tmp path name, and use
_PATH_TMP instead.)

A good example of a reasonable way to do this is in the
ftp sources.
