11.4 What is SD-UX and why does it replace /etc/update?

For HP-UX 10.0, the distribution of HP-UX software has been completely
revised.  HP Software Distributor 2.0 is used to install, update, remove, and
package HP-UX software.  This product is called SD-UX, often informally
shortened to just SD (even though there is also an unbundled product called
SD-OV offering enhancements over SD-UX).

All HP-UX 10.0 software is shipped on media compatible with SD.  SD media
can not be read by installation tools from previous HP-UX releases like
/etc/update, nor can you use previous installation tools with HP-UX 10.0
software.  The /etc/update program and its associated tools (/etc/updist,
/etc/filesets/, /system/, and so on) are obsolete, replaced by SD.

SD provides enhanced functionality, added features, and greater ease of use
than that provided by previous installation tools.  The concept of
installing, configuring, removing, and otherwise managing software has not
changed.  However, the set of commands and some of the capabilities that SD
brings to HP-UX are all new.

SD offers three user interfaces:

1.  An interactive graphical user interface available for the swinstall,
   swcopy, and swremove commands.

2.  An interactive user interface suitable for ASCII terminals (on S800)
    for the swinstall, swcopy, and swremove commands.

3.  A non-interactive command-line user interface for all commands.

For additional information on SD commands and features, see the individual SD
command manual pages, SAM's online help, the "Installing HP-UX 10.0" manual
(B2355-90050), and the "Managing HP-UX Software with SD-UX" manual
(B2355-90054).

The release notes shipped at 10.0 in /usr/share/doc/10.0RelNotes also contain
this information.
