Hi Steve-
Sorry for posting a single patch with a cover letter (a practice normally
frowned upon).
Here's the mount.nfs change that makes text-based NFS mounts the default,
deprecating the old legacy mount ABI for 2.6.23 kernels and later. It's
best to get this into the code base for people to start using long before
you plan to cut a new release of nfs-utils.
Text-based NFS mounts, as you know, are required to enable several upcoming
advanced NFS features, such as IPv6 support, NFS over RDMA, and local disk
caching. It will also make it simple to add support for new NFS mount
options.
The 2.6.23 kernel's text-based NFS mount support works for many basic
configurations. There are some regression nits that are cleaned up in
2.6.24.
Btw, will you continue hosting the nfs-utils git repository on
linux-nfs.org?

Get rid of the "-i" option for mount.nfs[4] and always use the text-
based mount(2) system call for kernel version 2.6.23 and later.
