+++ This bug was initially created as a clone of Bug #467349 +++

Description of problem:

When installing a patch, the first step is to unzip the patch into /tmp. However if there already is an old version of the archive in /tmp unzip hangs waiting for user input.

# up2date --get somepatch 
# Unzip it in /tmp
# up2date somepatch
[Freeze]

Packages installed on the Solaris box:

utility     RHATpossl                    pyOpenSSL 0.6
utility     RHATpythn                    python 2.4.1
utility     RHATrcfg                     rhncfg 5.1.0

utility     RHATsmart                    smartpm 5.1.1

The probably cause of the problem:

In line 63 of /opt/redhat/rhn/solaris/lib/python2.4/site-packages/smart/backends/solaris/pm.py
                cmdstr = "unzip %s -d %s" % (path, tdir)
Please update to read:
                cmdstr = "unzip %s -u -d %s" % (path, tdir)
Where -u does:
     -u   update existing files and create new  ones  if  needed.
          This  option  performs  the  same  function  as  the -f
          option, extracting (with query) files  that  are  newer
          than  those with the same name on disk, and in addition
          it extracts those files that do not  already  exist  on
          disk.   See  -f  above  for  information on setting the
          timezone properly.

Suggested fix:
make use of `mktemp -d` to create directories in /tmp
