freezeFS.py is a utility program that runs on a PC and converts an arbitrary folder, subfolder and file structure into a Python source file. The generated Python file can then be frozen as bytecode into a MicroPython image together with the Virtual File System driver vfsfrozen.py.

When the generated Python file is imported, the file structure is mounted with os.mount() as a read only Virtual File System, which can be accessed on the microcontroller with regular file operations such as open in "r" or "rb" mode, read, readinto, readline, seek, tell, close, listdir, ilistidr, stat.

If the deploy option is used, the files and folders of the frozen files are copied to the standard flash file system. This enables installing configuration and data files when booting the MicroPython image the first time.

An important topic is that opening files in "r" mode requires to buffer the file in RAM. However, many libraries such as web servers and json support reading text modes in "rb" mode, and no overhead is incurred.

lakeFS is an open-source tool that transforms your object storage into a Git-like repository. It enables you to manage your data lake the way you manage your code. With lakeFS you can build repeatable, atomic, and versioned data lake operations - from complex ETL jobs to data science and analytics. lakeFS supports AWS S3, Azure Blob Storage, and Google Cloud Storage as its underlying storage service. It is API compatible with S3 and works seamlessly with all modern data frameworks such as Spark, Hive, AWS Athena, DuckDB, and Presto.

Doesn't force you to use Docker.

GitHub - Drewsif/PiShrink: Make your pi images smaller! https://github.com/Drewsif/PiShrink

A shell script that takes a dd'ed image from a RasPi install and shrinks it down as far as possible so that it'll fit onto another, smaller microSD card. Used for cloning installs.

Remember, it won't work on a card, only a filesystem rip.

FUSE: Filesystem in Userspace https://github.com/libfuse/libfuse

A Linux driver system that allows unprivileged code to implement file systems. Because the file system drivers exist entirely out of kernel space, you can do some pretty crazy things with the file system block layer...

A utility which uses the FUSE functionality of the Linux kernel to implement NFS in such a way that it can spoof user credentials when mounting exported file systems so you can get access to files that you wouldn't be able to otherwise.
