Add flatpak and cloud-initramfs-growroot packages to all boards

We will need both flatpak and cloud-initramfs-growroot to be added to the images built for all boards.

• flatpak is needed because we assume that folks will install flatpaks on any board they have (emulated or physical)
• cloud-initramfs-growroot is needed because we want the size of the partition to expand to fill the space of the install medium, rather than leave the image at a static 3.6GB.

Did you check with flatpak added we still fit into the 3.8G we currently have?

I went ahead and tested it.

Yeah the flatpak package itself is pretty small so I didn't test it (although I should have to be sure). It's the runtimes that get you.

I see flatpak installed on last image, but it is still 3.6Gb, am I missing something?

Nope, as my comment just above yours states, the installed flatpak package itself is quite small (3MB). The last image contains the flatpak packge but no runtimes are installed yet.

You just need to grow the fs via resice2fs

Oh I think I misunderstood albfan's point :) Yes, just sudo resize2fs /dev/vda2 and you'll have a larger disk ready to use.
