I'm new to E-Smith but have a fair bit of general Linux experience. I have to do some work on two E-Smith machines, one firewall/gateway and one private server (mail/intranet mainly). Both machines are 5.5.
So anyway, three questions:
Are any issues/gotchas involved in upgrading directly from E-Smith 5.5 to 6.0?
Is SpamAssassin included in 6.0?
Also, can someone tell me where ipchains is configured in 5.5? There is a firewall running but I cannot find it's source anywhere ... nothing in /etc/sysconfig or /etc/e-smith/templates/etc/sysconfig or anywhere else I can think of. The init script is no help either

How/where are the default firewalls configured in E-Smith 5.5? Just a directory path will do!
Thanks
