The kickstart configuration file and system-config-kickstart tool
have an option for interactive kickstart installations, which I
ass-u-me-d would work much the same way autoyast automatic installs
do where I can abort the installation any time up to the point
where it says start-install, do you really want to do this?
My approach to writing GUI sysadmin tools is to have the GUI
collect the configuration parameters, then execute one or more
command line tools to do the real work. One of the few things I
really liked about AIX was that their SMIT tool displays the
commands, and logs them as well which can be very useful to
figure out what's going on under the hood. This is a bit easier
than ``touching'' a file to create a timestamp, doing something
with a GUI tool, the using ``find /etc -newer'' to figure out
what the GUI tool is actually doing.

That could be useful if I hadn't killed the install, only to find
myself with two empty disks without partition tables.
I just finished reinstalling the system, and now installing all
our OpenPKG based software on it. Doing this, I am reminded of
something worth venting about -- the aliases on rm, mv, and cp to
keep the children from doing dangerous things :-).
UNIX was not designed to stop you from doing stupid things,
because that would also stop you from doing clever things. --

No matter how much I may exaggerate it, it must have a certain amount of
truth...Now rumor travels fast but it don't stay put as long as truth
