emBSD isn't quite right for what I'm doing myself. I have
8M flash, and 16M ram to play with. Do we support
flash? If not, I suppose a low level block device
driver for it might suffice.
Now, flash tends to fail, due to the properties of
erase blocks and whatnot. Linux has initial ram
disks; does OpenBSD have anything similar? I've
seen an option for MFS, but not MFS_ROOT here.
I've seen RAMDISK_* options, but no real explanation
of how to use them, even in the source that implements
How can I tell the kernel to fetch some blocks, load them
into ram, then use that as the root filesystem, at boot
time? This is real flash btw; no IDE interface. Has 2
ethernet cards and 2 serial ports built in; low power
consuption AMD K5 cpu, and so forth. Oh, and a sweet
little 3DES chip built in for crypto.
