We're building a tool right now which includes booting a tiny Linux environment via PXE, and having it perform a number of system configuration operations without loading a larger system. (Formatting disks, creating filesystems, etc.) We've been planning to use BusyBox in this system, as having most of the system tools in one tiny static binary is obviously great in this context.
Problem, though: we've had a requirements change, and need support for creating ext3 (and maybe ext4) filesystems, which BusyBox does not support. Is anyone aware of a similarly self-contained binary tool which can be used for creating these filesystems? It doesn't need to also be BusyBox (I can include a few extra tools), but it can't require a bunch of dynamic libraries.
