I don't think you're going to find one single tool that does everything,
but you can find tools that do each piece well and glue them together.

I use systemimager + cvsup + tiny bit of shell for this, but maybe
radmin would do it better?

radmin or samhain?

Ganglia or nagios?

"integrity".  I assume you mean security stuff, so maybe samhain?

> rollback changes

I use systemimager for this (make a backup of the image, try it, if it
doesn't work, go back to the old image).

Nagios is what I use for this.

Uh, don't do it this way?  Instead, have your autoinstaller just do it.
And don't forget that installing is not the hard part; maintaining your
existing boxes is.

I don't know what this means.

Hrm, unfortunately I wouldn't call this "easy", yet.

I use dsh for this:

I've been wondering that myself, but no time yet to go do a checkout and
read.  :(
