Setting up a Swap File
----------------------
1. run make_swapfile in this directory:
. make_swapfile
Getting X working
-----------------
1. To get X11 working you will need to get your network up. The instructions
below assume your host (the computer you are running) has an ip of 192.168.1.4,
a uml ip of 192.168.1.2 and a tap device ip of 192.168.1.5.
2. If you haven't already done this, you will want to edit the
/etc/network/interfaces file using vi. This should be self-explanatory.
3. Load any modules required by your host system. If you decide to use
tap, do this:
modprobe ethertap
modprobe netlink_dev
4. Configure the device on your host system. Here the tap device is being
set to 192.168.1.5 and then routed to the host 192.168.1.4:
ifconfig tap0 192.168.1.5
route add -host 192.168.1.4 gw 192.168.1.5
5. The next time you start the uml kernel and boot the root_fs you will want
to give it options like this where HWaddr (see ifconfig) belongs to your
network device:
ubd0=/root_fs_debian_x11 root=/dev/ubd0 eth0=ethertap,tap0,HWaddr,192.168.1.5 mem=64M
Hint: An easier way to do this would be to use the UML box in gbootroot from
your host computer. No .. uml doesn't work within uml. :)
6. At this point you should be able to ping 192.168.1.4.
Hint: Check to make sure that uml_net came bundled with the uml kernel,
because this is what enables networking.
6. Run startx. It will ask for your host ip number.
That's it.

Hints:
Mount the host fs: mount -t hostfs none /mnt
mount -t hostfs none -o /home /mnt
