Dear SCO Customer,

Support Level Supplement (SLS) ptf7609c, the UnixWare 7.1.1 pkgadd Supplement,
addresses a problem where pkgadd(1M), used with the -p option, may fail as
shown below if the tape contains a large package whose table of contents is
written over more than one 512-byte block. The following is an example of a
failing command and the error messages:

   #pkgadd -p -d ctape1 MyPackage

   Installation in progress.  Do not remove the cartridge.

   UX:pkgadd: ERROR: attempt to process package from </dev/rmt/c0b0t2l0> failed
   - bad format in datastream table-of-contents

or:

   UX:cpio: HALT: Bad magic number/header.
   1 error
   UX:pkgadd: ERROR: attempt to process package from </dev/rmt/c0b0t2l0> failed

The data is read in 512-byte blocks. If the data is not terminated with
a null byte, it is possible for pkgadd to 'fall off the end' of the data.

Software Notes and Recommendations
----------------------------------

SLS ptf7609c should only be installed on:

        UnixWare 7 Release 7.1.1


Installation Instructions
-------------------------

1. Download the ptf7609c.Z file to the /tmp directory on your machine.

2. As root, uncompress the file and add the SLS package to your system
   using these commands:

Alternatively, SLS ptf7609c may be installed in quiet mode, that is, without
displaying the release notes and asking for installation confirmation. To do
this, use these commands:

        $ su
        Password: <type your root password>
        # uncompress /tmp/ptf7609c.Z
        # pkgadd -qd /tmp/ptf7609c all
        # rm /tmp/ptf7609c

3. There is no need to reboot the system after installing this SLS package.

The release notes displayed prior to installation can be found in:
