SUMMARY: !FW: WARNING SUN PATCH 108993-29 BREAKS REBOOT

GURUS:

HERE IS THE SUPPOSED FIX.  I HAVE NOT ATTEMPTED AS OF YET, BUT AM GOING TO
TRY.

- Backout patch 108993-29, although this re-introduces the security bug
   fixed in this release (BugID 4830525).

 OR

 - Replace /etc/lib/nss_files.so.1 with an old version

     Copy /etc/lib/nss_files.so.1 from a Solaris 8 system which doesn't
     have this patch installed yet.

     Alternatively, extract the file from the backout area:

     # cd /var/sadm/pkg/SUNWcsr/save/108993-29
     # uncompress -c undo.Z > /var/tmp/undo.datastream 
     # cd /var/tmp
     # mkdir undo.filesystem
     # pkgtrans undo.datastream undo.filesystem SUNWcsr
     Transferring <SUNWcsr> package instance
     # cp undo.filesystem/SUNWcsr/reloc/etc/lib/nss_files.so.1
          /etc/lib/nss_files.so.1-old

     Now that you have the file, replace the bad version:

     # cd /etc/lib
     # ln nss_files.so.1 nss_files.so.1-29
     # ln nss_files.so.1-old nss_files.so.1

     This workaround is confirmed on SPARC with etc/lib/nss_files.so.1
     from Solaris 8 FCS so it should work with all versions of the file
     prior to -29 on SPARC and x86.



HOPE THIS HELPS !!!
