What is Support Level Supplement (SLS) ptf9055c, the UnixWare 7.1.4
Maintenance Pack 4 Supplement?


Problem Fixed
-------------

  The following fix was first provided with ptf9055a and is also
  contained in ptf9055c:

  1. Fix a problem introduced in UnixWare 7.1.4 Maintenance Pack 4 that
     causes the command

       ln -s nonexistent newfile

     to fail inappropriately with

       UX:ln: ERROR: Cannot access nonexistent: No such file or directory

     when the target pathname ("nonexistent" in this case) doesn't exist.
     The "ln -s" command shouldn't care whether the target path (currently)
     exists.

  The following fix was first provided with ptf9055b and is also
  contained in ptf9055c:

  2. A memory corruption in dynamically loadable module subsystem is
     fixed which was caused by repeated loading and unloading of
     modules/drivers while an intervening open is initiated to get
     a hold on the driver.

  Fix provided in ptf9055c:

  3. A packaging error in ptf9055b resulted in a kernel build failure
     due to an undefined symbol after installing ptf9055b.

     Please Note: That the ptf9055b has been removed from the SCO 
                  download site due to this packaging error.
