The next patchset will fix that.
I'm dropping the tool name from the msgbox contents and putting it in
the title (e.g., '"Error: gpart") that way... even if the tool spits out its own
name (or not), we'll know what exactly what was going on by looking
at the title.

I believe the idea behind the script is that whatever you tell it to use will
be destroyed.
Allan, maybe perhaps we could add some code that attempts to dis-
assemble a graid to make the disk usable?
Johan, what would you be more apt to expect? That it killed your graid
or that it gave an error? (/me thinks what the recourse to the error might
entail -- going to partedit?)
