Configuring the kernels for the openrd and sheevaplug with a root path,
e.g.:

make buildkernel TARGET_ARCH=arm KERNCONF=DB-88F6XXX
ROOTDEVNAME=\"nfs:192.168.0.10:/mnt/ST340014A/diskless/arm-8-le/\"

does not fix the diskless boot problem; openrd:

Sending DHCP Request packet from interface mge0 (f0:ad:4e:00:61:58)
Received DHCP Ack packet on mge0 from 192.168.0.10 (accepted) (got root
path)
uhub2: 4 ports with 4 removable, self powered
mge0 at 192.168.0.16 server 192.168.0.10
subnet mask 255.255.255.0 router 192.168.0.1 rootfs
192.168.0.10:/mnt/ST340014A/diskless/arm-8-le hostname openrd
Adjusted interface mge0

The compile problems I had with the i386 was a lack of disk space.  I
have not yet started testing diskless booting since fixing this.
