Surely most mirror scripts pull down new content to a temporary file with
no general read privs, then atomically mv that temporary file to the name
of the updated file?
Similarly on the master ftp server. I see no locking issues, or need to
disconnect anybody. The only issue is that some people will have versions
of the ISO without tools.
Producing a new "with-tools" ISO sounds like a needless waste of mirror
operators' disk :)
