Version: 20070815.1-2+b2<br>
Severity: important<br>
<br>
On current Debian Test (Buster), uml-utilities seems to be broken in<br>
providing the console. This results in the UML instance not providing a<br>
shell to access it.<br>

A quick search on the UML HOWTO mentions:<br>
<br>
=x=x=x=x=x=x=x=x=x=x=x=x=x=x=<wbr>x=x=<br>
If you're running an up to date kernel with an old release of<br>
uml_utilities, the port-helper program will not work properly, so<br>
xterms will exit straight after they appear. The solution is to<br>
upgrade to the latest release of uml_utilities. Usually this problem<br>
occurs when you have installed a packaged release of UML then compiled<br>
your own development kernel without upgrading the uml_utilities from<br>
the source distribution.<br>
=x=x=x=x=x=x=x=x=x=x=x=x=x=x=<wbr>x=x=<br>
<br>
I am not sure how to take this. uml-utilities itself hasn't changed in<br>
quite a while.<br>
<br>
Also, the port-helper tool is already present.<br>
