I'm compiling a kernel with NFS_ROOT (and rarp and bootp support, JIC), should be done in a few hours (Sparc IPX, 20MB memory) > The third step is to export a Sparc tree (Sparc_root_path).

I'd hazard that I need to look at where it wants to mount and unmount, or fsck something. > The Sun's boot command is : > > boot net nfsroot=(NFS_Server_IP_addr):(Sparc_root_path) > > A so configured SS4 boots in 2 minutes on a 10Mb/s lan (about 30sec for the > Sun's diags, 30sec for initial RARP and Kernel TFTP and startup, and 1 min for > the system init).
