Increase swapfile size from 2G to 4G

[kristapsk]

Better to have more than less in our case. Official Void Linux recommendations (https://docs.voidlinux.org/installation/live-images/partitions.html#swap-partitions) for 2-8G systems is "equal to amount of RAM".

With too small swap space (I had old Nakamochi with 1G swapfile) user will notice freezing and slow screen unlock when system has too small amount of available memory. Then only workaround, unless you have ssh access, is turning it off and on again.

Walkthrough

The README.md swapfile creation command parameter is modified, increasing the swap space allocation from 2048 blocks to 4096 blocks. All other setup procedures and commands remain unchanged.

🐰 A swap of double, twice the hare,
From two to four, with greater care,
The README blooms, more space to spare,
Our memory buffers now breathe fair! ✨

89-89: Approve swap size increase; verify target Raspberry Pi RAM compatibility.

The parameter change is correct (4096 blocks × 1M = 4GB). However, the suitability of a 4GB swapfile depends on the intended Raspberry Pi model and its available RAM. The PR cites Void Linux recommendations to set swap equal to RAM for 2–8GB systems, but the README should document which Pi model(s) this image targets.

Could you confirm:

• Which Raspberry Pi model(s) does this image support?
• What RAM configurations are expected/tested?
• Is a 4GB swapfile appropriate for all supported models, or should this be configurable?

If the image is intended for Pi models with 4GB+ RAM, the change aligns well with the stated recommendations. If it supports lower-RAM models (e.g., Pi Zero with 512MB), a 4GB swapfile may be excessive or infeasible.
