Hello,

We are trying to setup RCS with SUID to prevent users other than the 
primary user from deleting revisions. We followed the directions in the 
man page for ci, but we are getting permissions issues when we try to 
checkout as one of the other users.

This is our setup:

  * Master user: sjc001
  * Group permitted to CI/CO: fte
  * Test alternate user in the fte group: sha001

This is the procedure we followed from the man page:

  * mkdir /usr/local/rcs-sjc001
  * cp /usr/bin/ci /usr/local/rcs-sjc001/
  * cp /usr/bin/co /usr/local/rcs-sjc001/
  * cp /usr/bin/rcsclean /usr/local/rcs-sjc001/
  * chmod go-w,u+s /usr/local/rcs-sjc001/*
  * PATH=/usr/local/rcs-sjc001:$PATH; export $PATH
