Don't worry, those features are present in TinyCore only.
Before expanding the filesystem we may create the swap partition. Frankly speaking I am not sure should we create it or not. Usually flash media is not recommended for usage as swap. Can we wait until someone will help us to answer this question? I don't feel quite sure I know the correct answer. In my opinion flash is not well suited for swap partitions. But maybe eMMC can handle it?
I understand that You want to continue as soon as possible, but if we will proceed now, then creating swap in the future will demand additional steps.
So what's on Your mind, let's continue without swap or will wait until someone will help us?
