(There may be a behavior difference between the 2.1 and 2.2/3.0 kernels
in this area, it seemed to work for me but I have a horribly hacked
select() that might have a bug in the handling of this)

if you do:
% cd /nfsdir
% mkdir -p foo/foo
% mv foo/foo .
nfs_sillyrename() self-destructs if you try to sillyrename a directory,
however nfs_rename() can be coerced into doing just that by the above
sequence of commands. To avoid this, nfs_rename() now checks that
v_type of the 'destination' vnode != VDIR before attempting the
sillyrename. The server correctly handles this particular situation
by returning ENOTEMPTY on the rename() attempt.
I asked if this was the correct fix for this on -hackers but nobody
ever answered.
This is a 2.2 candidate.
get installed.
The `install' target should only be overridden when the default one would
do something wrong and you're too lazy to fix the default one.
emitting the initial prompt.
This is useful in a number of circumstances :
- you have (a) stupid modem(s) that assert(s) DCD too soon.
- you have dialin users with stupid diallers and poorly
written chatscripts. (esp. some Winsock diallers)
BSD/OS also has this capability.

at device attach time, instead of allocating and freeing buffers as
necessary. But he or she forgot to remove the line that invalidated
the buffer when the device is closed. Therefore, after using the
device for the first time, the buffer was incorrectly invalidated and
that caused a page fault on the second, and subsequent uses.

assume that the timeval will be preserved. As the man page says:
".. it is unwise to assume that the timeout value will be unmodified
by the select() call." This happens on Linux and on my system at least.
Restore the clamp on the return value from rpc_dtablesize().. Some programs
(eg: ypserv) use this as an indication of how large svc_fdset is in their
hand-rolled svc_run() loops. The svc_fdset table is maintained by the
rpc library explicitly for compatability with such programs. (It uses
a different variable-sized bitmap itself internally)
this will make it less likely to misinterpret arrow keys as seperate
keys when running over anything slower than a console.
This has been talked about for a while, I hope it's long enough but not
too long to be annoying.

Note: potential bug here, It looks like there could be a null pointer
dereference depending on what has already been called to initialise some
shared data.
- kill non-FD_SETSIZE code

Note, there was a nasty bug with our old code here. It would trash the
stack if a fd > 31 was passed in. It was using a "long" as though it
was an "fd_set", ie: it was assuming that a long was 256 bits wide. :-(
This has been lurking here for a while, since the FD_SETSIZE #ifdef's
were first implemented.
