Many thanks to this fellows, who answered the following:
Jerry Hagon:
I use rdist to mirror a filesystem (/u) on a machine called bragg.
The filesystem is mirrored on a remote machine called landau with
directory name /export/users. Here is the disfile:
HOSTS = ( root@landau.ncl.ac.uk)
FILES = ( /u )
${FILES} -> ${HOSTS}
install -oremove /export/users ;
${FILES} :: stamp.landau
notify njph@bragg.ncl.ac.uk ;

Ann Rautenbach:
There's an excellent tutorial available on the internet, which helped
me set up rdist.

Gautam Das:
HOSTS = ( host1
host2
host3
)
FILES = ( /usr/bin/X11/netscape
/usr/local/lib/netscape/moz2_0.zip
)
${FILES} -> ${HOSTS}
You should read the manual page on rdist. If you don't you will regret
later. Rdist is a very powerful tool and must be used with full
understanding.

simple one:
#
# cp /opt/local on HostA to HostB
# ( run from HostA )
#
(/opt/local) -> (HostB)
install -R -w -y /;
notify spr@HostA;
# except /pathname;
# comment
===================================================================
another longer, but still simple one
#
# This copies files on HostA's root partition to another disk also
# mounted on HostA - this creates a copy of root that can be
# used in the event of failure of the primary root partition.
#
# fsck secondary root disk partitions
# mount secondary root disk (on /2nd_root)
#
#
# root_sync package
# files to keep synchronized between primary and secondary
# boot disk.
#
root_sync:
(/) -> (HostA)
install -R -w -y /2nd_root;
# files that are updated on each boot

David Foster:
f you get "version mismatch" error messages, chances are you have 'stty'
commands in your startup files that don't have an associated terminal
device when running rdist (hence the error messages). Put such commands
as such:
if ( $?prompt ) then # Only when interactive shell
stty -istrip
stty erase ^h
stty kill ^u
set history=32
endif
Also, make sure you have any references to variables like $TERM put in
a conditional statement like above, since these variables won't be
defined when using rdist (or rsh for that matter).
Hope this helps.
