Partitioning
============

Partitions system are configured with a standard schema using LVM, so
that they can be possibly changed afterwards.

By default the whole space available on the  first block device is used
and any existing partition is removed.
The default partition schema is:

   - create one primary ``/boot`` partition of 1Gb;
   - create the ``vg_root`` Volume Group that uses the rest of the disk;
   - on ``vg_root`` create the following logical volumes:
       - ``lv_root`` of 12 Gb size for ``/root``;
       - ``lv_var`` of 8 Gb size for ``/var``;
       - ``lv_var_log`` of 2 Gb size for ``/var/log``;
       - ``lv_tmp`` of 2 Gb size for ``/tmp``.


Custom Partitioning
-------------------
It is possible to customize the partitioning by using the ``partitions`` attribute on sysdb.

The ``partitions`` attribute can take two values:

   - ``manual``: this will not partition the disks and the installation process will wait for manual partitioning;
   - ``<URL>``: it is assumed to be a file containing the partitioning commands as used in kickstart.

If it is not possible to download the given URL the system fails-back to manual at installation time.
Please also note that no check is done on the URL content.
