I've gotten a few bug reports lately that if UDP is blocked at the

the change "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." -- in
other words, the bug is specific to the text interface. Does anyone
know why
this would be the case?
I specifically tested that when developing the text-based mount
interface, so if it doesn't work, it's a bug or a missed corner case.
Start with "mount.nfs -v" to see if the mount command tells you
anything interesting. Then do a raw network trace to see what's
failing during the mount version/protocol negotiation.
