Solaris 10 10/09 Installation Guide: Network-Based Installations

ProcedureHow to Modify the Miniroot (Example)

This procedure shows how to install a Kernel Update (KU) patch on a Solaris 10 10/09 miniroot image. On a system that is running the Solaris 10 OS, follow these steps, but note these details.

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 Solaris release, log in as superuser or assume an equivalent role.

  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 Solaris 10 10/09 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 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. Run the following command to 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 patchid

    patchid 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 – 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. Then, 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.

Next Steps

After you have set up the install server and patched the miniroot, you might need to set up a boot server or add systems to be installed from the network.
