I need to build a kernel that boots on a memory File System. The machine
should be a mips based system, and Well, I have absolutely no Idea of
how to do that.
I've been through a few Mailing list, looked in the kernel
documentation on the NetBSD internet site, and I have not found anything
about how to do that.

Well if anyone can help, or tell me where to find documentation....
Thanks anyway

Best regards
Frederic Gilliers

Check the various `ramdisk' build procedures under src/distrib/<port>.
Also look at the RAMDISK config files available for most ports. The manual
pages for md(4), mdconfig(8) and mdsetimage(8) are worth reading too.

Cheers, Steve

Some install kernels are built this way (the i386 install kernek for example).
Look at sys/arch/i386/conf/INSTALL and distrib/i386/floppies/
especially for things using md and mdsetimage (and man pages for these too).
vnd-related stuff are used to build the ramdisk image (and also the floppy
images).
