Upgrade #FreeBSD 8.2 to #FreeBSD 9.0

Ref: http://www.freebsd.org/releases/9.0R/installation.html

2 Upgrading FreeBSD
- 3 Upgrading from previous releases of FreeBSD
  Ref: http://www.freebsd.org/releases/9.0R/relnotes-detailed.html#UPGRADE
  The binary upgrade procedure will update unmodified userland utilities, as well as a unmodified GENERIC kernel distributed as a part of an official FreeBSD release.
  
  Host being upgraded have Internet connectivity.
  
  Upgrading FreeBSD should, of course, only be attempted after backing up all data and configuration files.
  
  Aquí lo que se debe rescatar son principalmente los archivos en /etc y /usr/local/etc
  - 3.2 User-visible incompatibilities

    - 3 Open Issues
      Ref: http://www.freebsd.org/releases/9.0R/errata.html
      - In some releases prior to 9.0-RELEASE, upgrading by using freebsd-update(8) can fail.

        Ver --> II. Problem Description freebsd-update When this bug is triggered, updates fail with the following error message: >
        
        The update metadata is correctly signed, but failed an integrity check. Cowardly refusing to proceed any further. Como consecuencia los sistemas afectados no se pueden actualizar a FreeBSD 9.0 usando freebsd-update. Seguir los siguiente pasos del documento 1), 2) y 3)
        
        # patch < /tmp/freebsd-update.patch
        
        Hmm... Looks like a unified diff to me...
        
        The text leading up to this was:

      - [amd64, i386] FreeBSD 9.0-RELEASE includes several changes to improve resource management of PCI devices.
      - A devctl(4) event upon arrival of a ugen(4) device has been changed. The event now includes ugen and cdev variables instead of device-name.
      - 9.0-RELEASE fails to configure an interface specified in the rc.conf(5) variable ipv6_prefix_IF ....
  - 3.2.2 Partition Metadata Integrity Check
    
    Puede suceder que se produzca el error: "GEOM_PART: Integrity check failed" de forma silenciosa y que el sistema no quiere bootear despues de upgrading a FreeBSD 9.0. En este caso seguir este punto.
  - 3.2.3 ATA/SATA subsystem now cam(4)-based
  - 3.2.4 Network Configuration Changes in /etc/rc.conf
  - 3.2.5 Openresolv and /etc/resolv.conf
  - 3.2.6 Disk Partition Management Utilities
- 2.2 Upgrading Using “FreeBSD Update”
  
  freebsd-update fetch/install ya fue realizado cuando se instalo el parche.
  - # freebsd-update upgrade -r 9.0-RELEASE
    Now the freebsd-update(8) utility can fetch bits belonging to 9.0-RELEASE. During this process freebsd-update(8) will ask for help in merging configuration files.
    
    The following components of FreeBSD seem to be installed: kernel/generic src/base src/bin src/cddl src/contrib src/crypto src/etc src/games src/gnu src/include src/krb5 src/lib src/libexec src/release src/rescue src/sbin src/secure src/share src/sys src/tools src/ubin src/usbin world/base world/catpages world/dict world/doc world/games world/info world/manpages world/proflibs The following components of FreeBSD do not seem to be installed:
    
    Does this look reasonable (y/n)?
  - # freebsd-update install
    
    Installing updates... rmdir: ///boot/kernel: Directory not empty Kernel updates have been installed. Please reboot and run "/usr/sbin/freebsd-update install" again to finish installing updates.
  - # shutdown -r now
    The system must now be rebooted with the newly installed kernel before the non-kernel components are updated.
  - # freebsd-update install
    After rebooting, freebsd-update(8) needs to be run again to install the new userland components:
    
    Installing updates...rmdir: ///usr/src/usr.sbin/freebsd-update: Directory not empty rmdir: ///usr/src/usr.sbin: Directory not empty
    
    Completing this upgrade requires removing old shared object files. Please rebuild all installed 3rd party software (e.g., programs installed from the ports tree) and then run "/usr/sbin/freebsd-update install" again to finish installing updates.
    
    The easiest way to do this is to run portupgrade (if you don’t have portupgrade, install it from ‘sysutils/portupgrade’): http://goo.gl/UlVqw
  - rm /var/db/pkg/pkgdb.db && pkgdb -Ffuv && portupgrade -afp
    
    I added the ‘p’-flag, as this allows you to run ‘portupgrade -afP’ on other nodes (assuming you have a shared ports-tree) and just install the packages without having to re-compile them. Ref: http://goo.gl/UlVqw
  - # pkg_version -v | grep "<" | awk '{ print $1}' | xargs -J % portupgrade % &
  - # freebsd-update install
    At this point, users of systems being upgraded from FreeBSD 8.2-RELEASE or earlier will be prompted by freebsd-update(8) to rebuild all third-party applications
  - # shutdown -r now
