Known Compatibility Exceptions from HP-UX 11.0 to 11i
Chapter 12
202
• Tighter Security for NFS Mounts
This change is necessary to improve the security of NFS mounts. Without this
change, when you export a file system using the root= option of exportfs,
NFS-clients on the root= option are allowed to mount the NFS file system even
when they don't appear on the rw= list and/or access= list. The new behavior
prevents NFS clients from mounting the file system unless they appear in either a
rw= and/or access= list.
• Export Filesystem (NFS) Security Defect Correction
This change corrects the NFS implementation so it conforms to industry practice
when exporting a file system. Well-behaved applications will not be affected by this
change. However, applications that assume that exporting a symbolic link to a file
system will result in the symbolic link being exported, rather than the directory to
which the symbolic link points, will fail that assumption. Shell scripts and
administrative processes may have to be changed to correct the assumption.
Software Distributor (SD)
• SD Bundle Algorithm Change
This change allows you to maintain a depot with multiple versions of a Software
Distributor bundle and automatically get the latest version of the bundle without
specifying a version qualifier. The install process no longer prints an error message
when you do not qualify which version of the bundle is intended to be installed.
• SD Automatic Generation of Depot or root Layout Version
This change allows you to maintain 10.20 and 11.x depots on an 11.x system. It
modifies the SD commands so they do not change the layout version of a depot or root
automatically. Any scripts or processes that rely on the automatic conversion to
layout_version=1.0 will be broken.
• SD Log Message Simplification
This change makes it easier for an administrator to identify real problems when
scanning the log files. The SD log files now contain less “noise” (error, warning or note
messages that contain no useful information).
• SD System Update Process
Although you will have to learn a new process, this change gives you a more robust
and easier to use the HP-UX 11i update process.
• SD Reduces Amount of Information from Program swlist
This change improves the performance of some swlist options. Extraneous data is
no longer displayed and the listing of bundles in a depot shows only bundles.
Applications that depend on the old format and behavior will have to be modified.
• SD Changes Behavior with Unknown Attributes
This change allows packagers to use new attributes in their software packages
without requiring SD to know the attribute. Specifically, the swpackage program will
no longer print error messages when an unrecognized attribute is encountered.
