I am not a big fan of Raspbian. Used to systems with more customizable and intuitive graphic environments, the option that Raspberry Pi offers us for its boards is the one that works best in terms of compatibility, but it leaves much to be desired in other aspects. In addition, on more than one occasion it will stop working after an update, something that will be impossible in Lampon Pi for being available only in Live mode.
All this is explained on the official page of the project, which we can access from this link. The image that they include on the main page is one thought to scare us or provoke some feeling, since it is Raspbian showing serious errors that could cause the system to stop working. For everything else, they explain that, at least right now, it is the only operating system for Raspberry Pi that works on Live mode, something similar to what distributions such as Knoppix And now we can do with practically anyone if we create a Live USB, which also usually serves to install the operating system.
Lampone Pi, the only system for Raspberry Pi in Live mode
Lampone Pi, at least this first version, is based on Debian GNU / Linux Buster (10), and it is an arm64 version of it that is designed for Raspberry Pi boards. They are not related to the Raspberry company, but they explain that it is the Raspbian Lite counterpart, with the difference that it is a Live 64bit operating system, although it has a persistent part:
On the technical side, it is a Debian arm64 derivative with a unique partitioning scheme designed to maximize strength against file system corruption - the ISO9660 system partition is read-only by design at the filesystem level. The data persistence partition contains only the delta - system updates and your data is there.
The data partition mounted on top of a read-only system partition makes the resulting operating system resistant to file system corruption. Also, you can make full system backups with just tar-ring only the files contained within that partition.
With all that explained, if you have a Raspberry Pi, have had Raspbian issues, and have an extra microSD card, I think the Lampone Pi is worth a try. The installation we can do with Etcher, as we explain in this article, or with the tool Imager official. Lampone Pi, whose support does not mention the Raspberry Pi 4, is available at this link.
