Hi,

I took quite some time to find out what's the problem here:

>> NetBSD/sparc Secondary Boot, Revision 1.14
>> (krille@lahksa, Wed Mar  2 21:50:57 CET 2005)
Booting netbsd
Trying BOOTP protocol... net_open: client addr: 192.168.1.4
net_open: subnet mask: 255.255.255.0
net_open: net gateway: 192.168.1.1
net_open: server addr: 192.168.1.2
ip address: 192.168.1.4, hostname: sparc.lan, netmask: 255.255.255.0,
gateway: 192.168.1.1
root addr=192.168.1.2 path=
Can't open NFS network connection on
`/iommu@f,e0000000/sbus@f,e0001000/SUNW,hme@0,8c00000'
Cannot load netbsd: error=13

I thought it may have been some misconfiguration with the services and tried
to find that. However, it turned out that everything was basically correct,
but the path to the NFS exported directory was too long so that an empty
path shows up above.

With Google I found the description here:
http://mail-index.NetBSD.org/port-sparc/2004/09/02/0008.html
(Would have been quicker if I had tried to ask Google earlier...)

The sparc (and other ports where appropriate) installation document should
mention this clearly to keep others away from this trouble. Once this is
committed please also issue the pullup request for netbsd-2.

Bye, Chris
