OK, there are other read-only distros too (the pfsense 'embedded' one is all but RO). Technically, if one could squeeze NanoBSD into 4-8MB, we could use the pfsense/ m0n0 XML-based config system, and just keep the config file in a single (or small number) of flash sectors at the end of the device. A similar configuration system that didn't require PHP would be even better. Then we just need to (perhaps) re-implement/replace the linux "mtd" system, and a F(F)FS can wait a bit. > Writing a flash-friendly-filesystem would be a good project. Indeed. Is there any reason to not approach Intel about a bit of 'funding' for FreeBSD on Xscale? They poured some cash on Wasabi for a similar effort on NetBSD.
