oz-cleanup-cache                                    Feb 2011                                 OZ-CLEANUP-CACHE(1)

       The Oz configuration file  is  in  standard  INI  format  with  several  sections.   If  any  section  or
       configuration  key  is  missing,  Oz will use a sensible default.  For true/false configuration keys, the
       values of "true", "True", "yes", or "Yes" can be used to turn the option on, and "false", "False",  "no",
       or "No" can be used to turn the behavior off.  The configuration file should have the following form:

           [paths]
           output_dir = /var/lib/libvirt/images
           data_dir = /var/lib/oz
           screenshot_dir = .
           sshprivkey = /etc/oz/id_rsa-icicle-gen

           [libvirt]
           uri = qemu:///system
           type = kvm
           bridge_name = virbr0
           cpus = 1
           memory = 1024
           image_type = raw

           [cache]
           original_media = yes
           modified_media = no
           jeos = no

           [icicle]
           safe_generation = no

       The  paths  section  defines  the  paths that Oz will use for storing data.  The output_dir key describes
       where to store the images after they are built, and the data_dir key describes  where  to  cache  install
       media  and  use  temporary storage.  Both locations must have a decent amount of free disk space in order
       for Oz to work properly.  The screenshot_dir key describes where to store screenshots of failed installs.
       The sshprivkey key describes where the ssh keys are stored, which are required by Oz to do  customization
       of the image.

       The  libvirt  section allows some manipulation of how Oz uses libvirt.  The uri key describes the libvirt
       URI to use to do the guest installation.  The type key defines what type of virtualization to  use.   The
       bridge_name  key  defines  which  bridge  Oz  should  place the guests that it launches on.  The cpus key
       defines how many cpus should be used inside the virtual machine.  The memory key defines how much  memory
       (in  megabytes)  should be used inside the virtual machine.  The image_type key defines which output disk
       type should be used; this can be any value that libvirt supports.

       The cache section allows some manipulation of how Oz caches data.   The  caching  of  data  in  Oz  is  a
       tradeoff  between  installation  time  and  storage  space.  The original_media key tells Oz to cache the
       original installation media so that it does not have to download it the next time an install for the same
       operating system is requested.  The modified_media key tells Oz to  cache  the  oz-modified  installation
       media  so that it does not have to download and modify it the next time an install for the same operating
       system is requested.  The jeos key tells Oz to cache the installed operating system  after  installation.
       This can significantly speed up subsequent installation of the same operating system, with the additional
       downside of the operating system getting out-of-date with respect to security updates.  Use with care.

       The  icicle  section  allows  some  manipulation  of how Oz generates ICICLE output.  ICICLE is a package
       manifest that can optionally be generated at the end  of  installs.   The  safe_generation  key  controls
       whether  Oz  uses  a  throwaway  overlay  file  while  generating  the ICICLE.  If it is set to "no" (the
       default), then Oz will boot up the guest at the end of the install and run the  appropriate  commands  to
       generate  the  ICICLE.  If it is set to "yes", then Oz will use a throwaway overlay file while generating
       the ICICLE.  After the ICICLE is generated, Oz will delete the backing file, leaving  the  original  disk
       image pristine.

       This  is  a  tool to remove all of the data that Oz has cached.  Because the data that Oz caches can grow
       fairly large, it may be worthwhile to periodically clean it up.  This is a simple script to do so.   Note
       that  if  you  do cleanup the Oz cache, subsequent operating system installs will be slower since Oz will
       have to re-download the installation media.

-c<config>
              Get the configuration from config file config, instead of the default /etc/oz/oz.cfg.  If  neither
              one  exists,  Oz  will  use  sensible defaults.  The config file is in standard ini format; for an
              explanation of the sections and keys, see the CONFIGURATIONFILE section.

       -d<loglevel>
              Turn on debugging output to level loglevel.  The log levels are:

              0 - errors only (this is the default)

              1 - errors and warnings

              2 - errors, warnings, and information

              3 - all messages

              4 - all messages, prepended with the level and classname

       -h     Print a short help message.
