    <H1>Building a RedHat root image</H1>

<P>
The image required to use User-Mode-Linux is just a normal set of executables.
These can be extracted from a RedHat distribution using the following proceedure.
</P>

<P>
There is a script in testing/utils called <CODE>uml-rhroot.sh</CODE>. It takes
two arguments:
<UL>
<LI> a directory in which to put resulting directory tree. 
<LI> a directory tree containing the RedHat distribution RPMs. This may be
  in one of three forms:
<UL>
<LI> a directory containing the directories "disc1" and "disc2". These 
  could be ISO images that are mounted loopback via, for instance:
<PRE>
<CODE>
mkdir -p /distros/redhat/7.2/disc1 /distros/redhat/7.2/disc1
mount -t iso9660 -o loop,ro /distros/redhat/7.2/enigma-i386-disc1.iso /distros/redhat/7.2/disc1
mount -t iso9660 -o loop,ro /distros/redhat/7.2/enigma-i386-disc2.iso /distros/redhat/7.2/disc2 
</CODE>
</PRE>
or even two real CDroms mounted somewhere. In the example above, use "/distros/redhat/7.2" as the distribution directory.
</LI>
<LI> a directory containing a "merged" disc1 and disc2 as suggested by RedHat in <A HREF="http://www.redhat.com/docs/manuals/linux/RHL-7.2-Manual/install-guide/s1-install-network.html#S2-INSTALL-SETUPSERVER">http://www.redhat.com/docs/manuals/linux/RHL-7.2-Manual/install-guide/s1-install-network.html under "Setting up the Server"</A>.
<LI> a directory containing all the required RPMs. (See <A HREF="uml-rhroot-list7.2.txt">list of RPMs</A>)</LI>
</UL>
</UL>
</P>

<P>The unpacked distribution will take approximately 133Mb. You will
  want to locate this on the same partition as your intended root
  trees for your User-Mode-Linux's as this will permit hard links to
  be used, saving disk space.  
</P>

<P>
  Because the RPM command used uses the chroot(2) system call and
  needs to change ownership of the files that it creates, it must be
  run as root. Afterward, you should chown the entire directory to the
  userid that you will be using for testing (i.e. probably
  yours). It should eventually suffices to make sure that you can read
  every file.
</P>

<P>
You should be able to chroot to this directory and run programs. If
you can not at least run ls, then there is a problem.
</P>
<P>
Expect a couple of errors about install-info.
