Miniroot preparation
This section describes the procedure for customizing a miniroot and provides an example set of
modifications that are typically required for ProLiant servers.
Prerequisites for preparing a miniroot
To prepare a miniroot for ProLiant server deployments, the following prerequisites must be met:
• System must be running Solaris 10 1/06 or higher—An x86-based system running Solaris is
required for use as the staging system.
• Disk space on the staging system—Disk space must be approximately two to three times the size
of an uncompressed miniroot (approximately 300 MB to 500 MB).
• Miniroot—The miniroot you are modifying must be available to the staging system. A stock
Solaris miniroot is available on the media (DVD or the first CD), and under the installation media
root directory on the install server as .../boot/x86.miniroot.
• Modifications—The set of packages you are installing, or other modifications, must be available
from the staging system. For a list of required modifications for ProLiant servers, see “Deploying
ProLiant servers.”
Preparing a miniroot
A general procedure for customizing a miniroot is provided here. An example for ProLiant servers is
provided in the following section.
1. Unpack the miniroot to a temporary directory (in this example, /var/tmp/mr):
# /boot/solaris/bin/root_archive unpack .../x86.miniroot
/var/tmp/mr
2. The miniroot is unpacked and expanded under /var/tmp/mr (the root of the Solaris instance),
and can be modified as necessary. For example, packages can be installed by adding a -R
/var/tmp/mr option to pkgadd(1M).
NOTE: The stock miniroot does not contain a record of which Solaris packages are already
installed. As a result, pkgadd(1M) can report that dependencies have not been met when
installing additional packages. You must verify that dependencies are met. However, in all the
specific examples provided in this guide, you can ignore dependency warnings from
pkgadd(1M) because the stock miniroot meets all such dependencies.
3. When modifications are complete, repack the modified miniroot under /var/tmp/mr into
/var/tmp/x86.miniroot.new:
# /boot/solaris/bin/root_archive pack /var/tmp/x86.miniroot.new \
> /var/tmp/mr
/var/tmp/x86.miniroot.new is the modified miniroot, packed and ready for use.
Repacking the Miniroot might take several minutes to complete.
NOTE: There is a known issue with Solaris 10 10/08 for which a miniroot with a name other
than x86.miniroot cannot be unpacked after creation. If you need to make modifications to a
custom miniroot, you must temporarily rename it to x86.miniroot to use the root_archive
tool.
