I'm updating my scripts for building RHL-derivative distributions to work with the newest anaconda available, and I have run into the new "Media Check" feature. This is a great feature, and I would like to be able to use it in my distro. Looking through the anaconda-runtime package, I found the implantisomd5 and checkisomd5 programs. These are standalone binary programs which, as far as I can tell, none of the provided scripts use. Can anyone provide guidance as to the usage of these programs, or in a larger sense, how to handle media check? On another note, I have noticed for both anaconda 7.2 and the latest versions, it can use a program called /usr/bin/runroot. However, I can find no reference to this program anywhere else -- not on rpmfind, not on google, not on freshmeat. Does anyone know what this program is and what is does? Thanks. Peter
