rwarchivefs
A read-write mountable archive filesystem, similar to squashfs, but read-write and more wasteful, based on fuse and a sqlite archive.
The primary goal of this is that it should be fun to make, and should be educational for future work with rwtagfs.
This will be a filesystem as a sqlite archive, but intended to be compressable and easy to work with both as a live filesystem and as an archive that can be easily extracted through Sqlite.
This will have the following features:
- Mountable as a FUSE filesystem
- Extractable as an archive
- Full POSIX ACLs, attributes, and extended attributes
- Block-based file storage for more efficient file writing, and sparse files.
- Full compression support, with each block individually compressed, so a single file can be saved with different compressions, and changing compression doesn't break anything.
- Full consistency ensured by SQLite transactions.
Basically, we want an efficient, compact, read-writable squashfs as a SQLite archive, with a reference implementation written in Rust.
