Updating best practices

[Ugo Bellavance-2]

Hi,

        I thought about using a simple script to update my DCC installation
once a week.

        Something like:
============================
#! /bin/bash
#

# Lets not all hit the servers at the same time sleep $RANDOM
sleep $RANDOM

# update dcc
/var/dcc/libexec/updatedcc -K
=============================

Does it make sense?  Is there more doc than the --help switch?  It is
not very usefull:

updatedcc: [-xvU] [-e ENV=VAL] [-c CONF=VAL] [-s base-URL] [-V x.y.z]\
         [-C pfile] [-T make-tgt]

-K is not even there...

Thanks,

Yes.

I've thought of adding mechanism to `updatedcc -K` to sleep a random
number of minutes between 0 and 30, but it does not seem necessary yet.

Recent versions have a hack that keeps `updatedcc -K` from working more
often than once per week.  That has solved some excess bandwidth problems
I was having at one server.

There are comments in the script itself.

thank you for pointing that out.  I will fix it.
