HOWTO: Patch Solaris 10 Wanboot Miniroot Image

/howto-patch-solaris-10-wanboot-miniroot-image 2007-07-10T16:49:43+01:00

Details on patching the Solaris wanboot/netinstall miniroot image for jumpstart are a bit scarce as, generally speaking, there should be no reason to patch the wanboot miniroot. However due to various issues with Solaris 10 releases, patching of the miniroot has become necessary.

This post details how to patch the wanboot/netinstall miniroot image.

1. Create just the boot image:

# /cdrom/cdrom0/s0/Solaris_10/Tools/setup_install_server -b /path/to/boot-dir

2. Patch the boot image:

# PKG_NONABI_SYMLINKS=true patchadd -C /path/to/boot-dir/Solaris/Tools/Boot <patchid>

... where <patchid> is the patch ID, eg 118833-36.

3. Generate the wanboot image:

# cd /path/to/boot-dir/Solaris_10/Tools
# ./setup_install_server -w /path/to/miniroot-dir/ /path/to/tmp-dir

4. Copy miniroot to desired location

# cp /path/to/miniroot-dir/miniroot /var/apache/htdocs/wanboot10/miniroot

You miniroot should now be patched.

Here's the output you can expect to see (it may differ slightly on your system):

# cd /cdrom/cdrom0/s0/Solaris_10/Tools/
# ./setup_install_server -b /export/s10-boot

         The WAN boot Image file has been placed in

         Ensure that you move this file to a location
         accessible to the web server, and that the
         WAN boot configuration file wanboot.conf(4)
         for each WAN boot client contains the entries:

                         where <URL> is an HTTP or HTTPS URL
                         scheme pointing to the location of the
                         WAN boot CGI program

                         where <miniroot> is the path and file
                         name, relative to the web server
                         document directory, of 'miniroot'

         You should also make sure you have initialized
         the key generation process by issuing (once):

                 # /usr/sbin/wanbootutil keygen -m

Install Server setup complete

You may get the following error when running the "setup_install_server -w":

ERROR: The product distribution does not contain
        a product table of contents

This will be due to the lack of .cdtoc in /export/s10-boot. You can copy this directly from the cdrom.

NOTE: If you intend on applying the kernel patch (118833-36), please be sure to read note #78 in the README (you do read the READMEs don't you?).
