	Warning

	During the installation, you will be asked about the partition scheme.
	Don’t use LVM partitions. They are not supported by snf-image-creator.

-> Not sure if that applies here.

http://www.synnefo.org/docs/snf-image-creator/latest/usage.html#image-partition-schemes-and-shrinking

	When image shrinking is enabled, snf-image-creator will shrink the last
	partition on the disk. If this is a swap partition, it will remove it,
	save enough information to recreate it during image deployment and
	shrink the partition that lays just before that. This will make the
	image smaller which speeds up the deployment process.

	During image deployment, the last partition is enlarged to occupy the
	available space in the VM’s hard disk and a swap partition is added at
	the end if a SWAP image property is present.

-> Maybe a single / partition and a possible swap space at the end ?

part / --fstype ext4 --size=1000 --asprimary --ondisk=sda
part swap --size=128 --asprimary --ondisk=sda --fstype swap 

The above docs have to do with the 'snf-image-creator' tool which
we use to create our images. After the image is prepared this tool
does not get in the path. The image gets deployed and customized
by the 'snf-image' tool:

http://www.synnefo.org/docs/snf-image/latest/

However, since snf-image does not operate on LVM partitions,
that's why snf-image-creator doesn't support LVM too.

Regarding swap:

The image doesn't need to have a swap partition, since snf-image
has a corresponding option to add one dynamically. That's why
snf-image-creator removes the swap if it finds it at the end and
sets that property accordingly during registration of the image.
If the swap is not at the end, it leaves it as is. So, the best thing
to do in our case is to *not* have any swap at all in the image.

Thanks,
Constantinos


P.S.: snf-image's SWAP property should have been documented
here:
http://www.synnefo.org/docs/snf-image/latest/interface.html#image-properties-img-properties
but I just saw it's missing. We'll be patching the docs right away.

Cheers,

Tru
