o Now we handle target modules correctly
...
o Moved the linear target into its own module (not really because it needs to
be there, but because its useful to have a simple example so people can see
what we are doing)
Btw, this needs testing properly.

o first sattab at custom fs. Very rough ATM.
...
Mount the dm-fs filesystem on /device-mapper (will fix later). mkdir
to create a device, inside that directory every file you create is a table
file. If there are errors <table>.err will appear automagically. Mv a table
file to ACTIVE to activeate the device. I'm not happy with mv being the
binding command, symlink would be better.
