I just booted FreeBSD-current diskless, using NFS root, and I ended
up having issues because by default, NFS root is only v2.
One of things that happened was disk space available was listed as
-138G, or -144830429K. I assume this is because the server is reporting
TBs instead.
If I mount via mount_nfs, the sizes are normal/correct because it mounts
v3.
The other issue that I ran into is that NFSv2 can't access >4GB files
(or create them).
Anyone object to adding BOOTP_NFSV3 to GENERIC? Or maybe making it a
tunable that defaults to set, because it seems a bit crazy to default
to v2 these days.
This option was added in 432aad0e in 1997 so that the nfs_diskless
structure didn't need to be filled out. Does anything even
populate/fill it out anymore? I saw code in i386/i386/locore.s that
does this, but it doesn't appear anywhere else.
There also appears to possibly be a way via mount options, but I can't
see where it's documented to set them.
