Try building a kernel without the above options, but with
options NFS_ROOT
specified. I think that's what most pxeboot users do and it was what
I had assumed when I looked at the code.
If that doesn't fix the problem...I haven't got a solution for you, rick
I use:
options BOOTP_NFSV3 # Use NFS v3 to NFS mount root
Looking at the code, it appears that BOOTP_NFSROOT doesn't set mygateway
in the nfs_diskless structure, which would explain why the mount of root
in the kernel doesn't work.
I think using NFS_ROOT but not the BOOTPxxx options will work around this
or you could test the following patch and see if it helps. (Testing the
patch would be appreciated, since I don't have any way to test across
multiple subnets and it would be nice to have a fix for the BOOTPxxx
cases.)
