Defines the size of the `swap` volume. The default is the size of the
installed memory, minimum 4 GB and maximum 8 GB. The resulting value cannot
be greater than `hdsize/8`.
++
+NOTE: If set to `0`, no `swap` volume will be created.
`maxroot`::
`datasize = hdsize - rootsize - swapsize - minfree`
+
Where `datasize` cannot be bigger than `maxvz`.
++
+NOTE: In case of LVM thin, the `data` pool will only be created if `datasize`
+is bigger than 4GB.
++
+NOTE: If set to `0`, no `data` volume will be created and the storage
+configuration will be adapted accordingly.
`minfree`::
