libdevmapper like library for NetBSD

[Adam Hamsik <haaaad%gmail.com@localhost>]

Hi folks,

I found some time and I tried to write library [1] for device-mapper  
driver.
This library can't be used with linux lvm2tools but we can create/ 
manage dm devices
without gpl2 code in base we can replace dmsetup with dmctl now. Later  
we can
replace lvm2tools with our own version.

For now there is no other consumer of this library then dmctl binary  
which is used
to configure dm devices.

HOWTO:

#dmctl create test <- Create dm device with name test

#dmctl reload test <- Load table to device test
0 100 linear /dev/wd1a 384

#dmctl remove test <- remove device test

[1]www.netbsd.org/~haad/libdm09242008.tar.bz2

Do you have any suggestions ? I haven't write any library interface/ 
dmctl documentation yet.
But I will look at it when I will be able to stabilise interface and  
dmctl more.

Regards

Adam.
