The following transcript comes from a 2.3.99-pre8 kernel configured on
the command line as follows:
Six block devices (the ubd0 through ubd5 arguments) attached to:
My Slackware root filesystem, which will boot the system
My SuSE root filesystem
A 64 Meg swap file
A kernel source pool
The physical machine's CD-ROM drive
An lmbench pool
128 Meg of physical memory
The host end of the network device connection is set to 192.168.0.100
