Optionally create swap space inside built images
Created by: SunilMohanAdapa
Most of our targets have low memory (~512Mb) and some our applications can take quite some memory (Apache, ownCloud) depending on the load. Even though most of the single board computers have slow disks, it is good to have the option of having swap space. Swap space can be a bit better for virtual machines too.
A feature request in vmdebootstrap aims to add support for swap. Once that is done, we can enable the right flags in freedom-maker.
