I have a system running 4.3-RELEASE-p20 and another machine freshly
installed from the 4.3-RELEASE CD.  I want to do the classic export
src and obj and then do an installworld over the NFS mount.

It fails early on with an "errno 71".

The system message for error number 71 is:
    Too many levels of remote in path

Here's the command that fails:

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
===> lib/libcom_err
cd /usr/src/lib/libcom_err &&  install -C -o root -g wheel -m 444  /usr/src/lib/libcom_err/../../contrib/com_err/com_err.h /usr/include
cd /usr/src/lib/libcom_err &&  install -C -o root -g wheel -m 444  /usr/src/lib/libcom_err/../../contrib/com_err/com_right.h /usr/include
install -c -o root -g wheel -m 444   libcom_err.a /usr/lib
install -c -o root -g wheel -m 444   libcom_err_p.a /usr/lib
*** Error code 71

Stop in /usr/src/lib/libcom_err.

If I cd to "/usr/src/lib/libcom_err" and type either of those first
two install commands by hand I get the same failure.

Here's the contents of "/etc/exports" on the server:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
#
# $ID:$
# NFS exported filesystems
#
/usr/src -ro -maproot=0:0 eciweb1
/scratch/obj -ro -maproot=0:0 eciweb1
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
The mount commands on the client were:
    mount -r -t nfs ecibsd1:/usr/scr /usr/src
    mount -r -t nfs ecibsd1:/scratch/obj /usr/obj

So, how does one increase the depth allowed in a remote path?
