The mconsole protocol needs to be versioned.
<p>
The next version of the protocol needs to be more packet-oriented than
it is now. In order to pass an arbitrary amount of data back to the
client, we need to support replies with multiple packets and to be
able to tell when the output is finished.
<p>
The current client needs improving:
<ul>
<li>
It should be able to control multiple UMLs
</li>
<li>
It should be able to detect new UMLs as they come up
</li>
<li>
Command history should work and should be saved from one session to
the next
</li>
</ul>
The mconsole should be able to receive console output and
notifications of panics. It should have some sort of intelligent
interface for letting the user see or ignore the console output.
<p>
There probably needs to be a GUI mconsole client. Emacs and IRC
mconsole clients would also be cute.

Its protocol should be versioned.
<p>
There needs to be an output socket for each client, rather than the
single socket that exists now. This is because one client that slowly
receiving packets could cause the socket to nearly fill up, causing
packets to another client to overflow it and lose packets. In this
case, the slow UML will unfairly cause a different UML to lose packets.
<p>
It should be able to act as a gateway to the host.
<p>
It should be able to communicate over UDP sockets as well as unix
sockets

It should be able to communicate with uml_routers on other hosts

Someone who understands how RPM and debs work should look at the UML
packages and at least figure out what's wrong with them.
<p>
Better documentation needs to be installed with them. The HOWTO
currently isn't build and installed. There also needs to be a README
installed in /usr/lib/uml which at least describes what to do with the
module tarballs.
<p>
The UML test harness should be packaged up somehow. My current
thinking is that the tarball could be part of the packages, the
install scripts would check for the presence of perl, and if it's
there, unpack and install the test harness and test cases in the same
way that modules from CPAN are installed.
<p>
And the test suite has not been worked on for quite a while. The UML
module should be updated so it can be an mconsole client. The test
suite should be turned into a real set of tests which can be run as
part of the normal build process.

James Stevenson has written some handy gdb scripts which make it easy

The mkrootfs script needs to be able to create bootable filesystems
from Debian and Debian-based media.
<p>
It also needs to be able to construct special-purpose filesystems,
such as minimal filesystems that run a single service, such as Apache,
sendmail, or bind.
<p>
A GUI version of mkrootfs might also be nice.
