An easy way?  Okay:

* shutdown coLinux  [ "shutdown -h now" ]
* change directory to your coLinux installation  [
C:\coLinux by default ]
* copy "Debian-3.0.r0.ext3.1gb" to "cobd.1"
* copy "default.colinux.xml" to "colinux.xml"
* edit colinux.xml to add device index #1, like:

<?xml version="1.0" encoding="UTF-8"?>
<colinux>
    <block_device index="0"
path="\DosDevices\c:\coLinux\Debian-3.0r0.ext3.1gb"
enabled="true">
    </block_device>
    <block_device index="1"
path="\DosDevices\c:\coLinux\cobd.1"
enabled="true">
    </block_device>
    <bootparams>root=/dev/cobd0</bootparams>
    <image path="vmlinux"></image>
</colinux>

* startup coLinux-daemon with the new config  [
"colinux-daemon -d -c
colinux.xml" ]
* login as root
* $ mkdir /mnt/cobd1
* $ mkfs.ext3 /dev/cobd1
* $ mount /dev/cobd1 /mnt/cobd1
* $ cd /mnt/cobd1
* $ dd if=/dev/zero of=swapfile bs=1024 count=262144  
  [ 1024*bs*256=256MB
swapfile ]
* edit /etc/fstab and add entries for cobd1 and the
swapfile in mount order,
like:

/dev/cobd0 / ext2 defaults 0 1
proc /proc proc defaults 0 0
/dev/cobd1 /mnt/cobd1 ext2 defaults 0 2
/mnt/cobd1/swapfile none swap defaults 0 0

* $ mount -a
* $ swapon -a

If you used my numbers, you have an extra 256MB of
memory.  Since coLinux
runs on NT, there is no need to format a swap
partition or device unless you
need the extra speed with raw access.  The swapfile
should perform
practically the same as a swap device.   And, you can
use the extra rest of
cobd1 as a regular mounted drive with a swapfile.

If you want a larger cobd1 filesystem before you make
cobd1, from NT:

copy
Debian-3.0.r0.ext3.1gb+Debian-3.0.r0.ext3.1gb+Debian-3.0.r0.ext3.1gb+Debian-
3.0.r0.ext3.1gb cobd.1

That would give you a 4GB device.

I thought I would make a utitility to do these steps
easier.  Still
thinking...
