Patching the Miniroot Image (Example)

This example describes the steps to patch a miniroot image to create a modified miniroot.

In this example, you perform the unpacking and packing of the miniroot on a system that is running the current release.

How to Modify the Miniroot (Example)

This procedure shows how to install a Kernel Update (KU) patch on an Oracle Solaris 10 1/13 miniroot image on a system that is running the Oracle Solaris 10 OS. Note these details:

• jmp-start1 – A network installation server that is running the Solaris 9 OS

• v20z-1 – A system that is running the Oracle Solaris 10 OS, with GRUB implemented

• v20z-1:/export/mr – The unpacked miniroot location

• v20z-1:/export/u1 – The installation image that was created, so it could be modified

The network installation image is located at /net/jmpstart1/export/images/solaris_10_u1/Solaris_10/Tools.

1. On a system that is running the current Oracle Solaris release, log in as superuser or assume an equivalent role.

   ---

   Note - Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

   ---

2. Change to the directory where you want to unpack the miniroot and place the network installation image.

   # cd /net/server-1/export

3. Create the installation and miniroot directories.

   # mkdir /export/u1 /export/mr

4. Change directories to the Tools directory where the Oracle Solaris 10 1/13 installation images are located.

   # cd /net/jmp-start1/export/images/solaris_10/Solaris_10/Tools

5. Create a new installation image, and place the image on the system that is running the current Oracle Solaris release.

   # ./setup_install_server /export/u1
   Verifying target directory...
   Calculating the required disk space for the Solaris_10 product
   Calculating space required for the installation boot image
   Copying the CD image to disk...
   Copying Install Boot Image hierarchy...
   Copying /boot  netboot hierarchy...
   Install Server setup complete

   The installation server setup is now complete.

6. Unpack the miniroot.

    # /boot/solaris/bin/root_archive unpackmedia /export/u1 /export/mr

7. Change directories.

   # cd  /export/mr/sbin

8. Make a copy of the rc2 and the sulogin files.

   # cp rc2 rc2.orig
   # cp sulogin sulogin.orig

9. Apply all required patches to the miniroot.

   patchadd -C /export/mr /export patch-ID

   patch-ID specifies the patch ID that you want to apply.

   In this example, five patches are applied to the miniroot.

   # patchadd -C /export/mr /export/118344-14
   # patchadd -C /export/mr /export/122035-05
   # patchadd -C /export/mr /export/119043-10
   # patchadd -C /export/mr /export/123840-04
   # patchadd -C /export/mr /export/118855-36

10. Export the SVCCFG_REPOSITORY variable.

    # export SVCCFG_REPOSITORY=/export/mr/etc/svc/repository.db

    ---

    Caution - The SVCCFG_REPOSITORY variable must point to the location of the unpacked miniroot's repository.db file. In this example, that location is the /export/mr/etc/svc directory. The repository.db file is located in the directory /etc/svc under the unpacked miniroot. Failure to export this variable results in the modification of the live repository, which prevents the live system from booting.

    ---

11. Modify the miniroot's repository.db file.

    # svccfg -s system/manifest-import setprop start/exec = :true
    # svccfg -s system/filesystem/usr setprop start/exec = :true
    # svccfg -s system/identity:node setprop start/exec = :true
    # svccfg -s system/device/local setprop start/exec = :true
    # svccfg -s network/loopback:default setprop start/exec = :true
    # svccfg -s network/physical:default setprop start/exec = :true
    # svccfg -s milestone/multi-user setprop start/exec = :true

    For more information, see the svccfg(1M) man page.

12. Change directories and restore the original copies of the rc2.orig and sulogin.orig files.

    # cd /export/mr/sbin
    # mv rc2.orig rc2
    # mv sulogin.orig sulogin

13. Pack the modified miniroot that contains the changes you made. Place the modified miniroot in the /export/u1 directory.

    # /boot/solaris/bin/root_archive packmedia /export/u1 /export/mr

    This step essentially replaces /export/u1/boot/miniroot directory, along with some other necessary files.
