HP-UX System Administrator's Guide: Overview

Other Software Operating System Installation Technologies
There are several other pieces of the software installation picture:
Ignite/UX If you need to install a common set of HP-UX software on
multiple systems and would like to do it at one time, from
one location, you can use Ignite/UX. See “Ignite-UX”
(page 114).
update-ux The update-ux command updates the HP-UX operating
system from new HP-UX media. See the manpage
update-ux(1M) for details.
Dynamic Root Disk Dynamic Root Disk is an HP-UX system administration
tool set used to clone an HP-UX system image to a disk
other than that from which the system is currently booted,
for purposes of software maintenance and recovery. In this
way, you can install software and patches to a clone of your
current system without affecting the running system. Then,
when an opportunity to reboot the system is available, the
patched or updated clone can be booted. This reduces
system downtime to just the time it takes to reboot to the
clone. Also, if necessary, the changes can be quickly backed
out by simply rebooting to the original clone.
Software Manager Software Manager is used by Ignite-UX and Update-UX to
perform software installation. Software Manager improves
software selection, provides support for OEs, and provides
update support for preview and a terminal user interface
(TUI). See the manpages swm(1M) and swm-oeupdate(1M)
for more details.
Further Reading about Software Maintenance on HP-UX
See also the following manpages for additional information about various software
packaging utilities supported by HP-UX:
ar(1)
The ar command maintains groups of files combined into a single archive
file. Its main use is to create and update library files as used by the link
editor (see ld(1)). It can be used, however, for any similar purpose.
cpio(1)
The cpio command saves and restores archives of files on magnetic tape,
other devices, or a regular file, and copies files from one directory to
another while replicating the directory tree structure.
gzip(1)
The gzip command compresses files to save disk space. It can compress
single files or whole directory structures, packaging the files of the directory
structure into a single archive in the process.
pax(1)
The pax command extracts, writes, and lists archive files and copies files
and directory hierarchies. A more contemporary utility, pax performs
