I thought of this after I sent the message. Actually, the thing that
hit me was that if it worked I would be left with Sendmail still on
the system anyway. Which could lead to conflicts with qmail.

While I was asking about upgrading, I tend to agree with Gordon here.
It is always a good idea to do a fresh install rather than an
upgrade. And e-smith make it easy to save the "tweaks" from one
version to another. I just copy the contents of /etc/e-
smith/templates-custom to a floppy before doing an install of a new
version, and then copy them back after.
I mean you gotta love that!!
The other thing about doing a fresh install is that from a security
point of view, its better. In the event that your system has been
cracked without your notice, doing a clean install locks the intruder
out again.
