Patching the boot miniroot

Assume that the setup is according to Custom JumpStart framework setup.
Consider that no operations have happened yet from /install/Solaris_10/Tools.
The booting miniroot should be unpacked to a subdirectory, not a ZFS dataset.
  
IMPORTANT
It can be considered best practice to patch the boot miniroot as soon as possible.
It's known to be necessary when performing a flash install of an updated ZFS-root image.
/install/Solaris_10/Tools should already exist as per the previous assumptions.
For correct patchadd behavior patch 119255-86 / 119254-86 must be installed.
  
The whole operation is as follows:
  
# mkdir /patch/miniroot
# /boot/solaris/bin/root_archive
    unpackmedia /install /patch/miniroot 

# cp -p /patch/miniroot/sbin/rc2{,.0}
# cp -p /patch/miniroot/sbin/sulogin{,.0}
  
# smpatch download -d /tmp -f -i 147441
147441-23 has been validated.
  

# patchadd -C /patch/miniroot /tmp/147441-23 

Patch 147441-23 has been successfully installed.
See /patch/miniroot/var/sadm/patch/147441-23/log for details

Now, other boot and/or JumpStart servers can be more easily updated.
Assuming that the updated server js-01 can (rw) mount js-02:/install:
  

js-01 # cd /install
js-01 # find boot Solaris_10/Tools/Boot |
          cpio -pdum /net/js-02/install
