NAME

       oz-cleanup-cache - tool to remove cached oz data

SYNOPSIS

       oz-cleanup-cache [OPTIONS]

DESCRIPTION

       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.

OPTIONS

       -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 CONFIGURATION FILE 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.

CONFIGURATION FILE

       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.
