Thanks to those who quickly responded, especially Matthew Stier and Francisco
Roque who suggested looking at the /net automount. Disabling autofs allowed
the sudo command to finish as anticipated, but that is not a real solution as
I use /net to access other systems without going through NFS mount bother. I
tested several levels of 1.6.9 and all had the same issue. The latest,
1.6.8p9, does not have this issue and does not lstat lots of things for
root.sh. Therefore, the program was not hacked and does not need a recompile.
The lstat for root.sh must be a new "feature" for 1.6.9. So I'm going to use
1.6.8 for now.

Subject: sudo hangs looking for /net/root.sh
Situation:
Sol 10 - 0807 on SPARC
Sudo version 1.6.9p5 from sunfreeware.com
As any valid sudo user, including root, run: 'sudo ls' (or any other command)
Command hangs a bit, but completes. If same command run immediately after
first completes, no hang. If run after a bit (at least 15 seconds) hangs
again. Truss of sudo shows a long pause running lstat for /net/root.sh. Any
ideas?
