The files under this directory were written by Kapil Hari Paranjape
<kapil@imsc.res.in> and are based on pbuilder by Junichi Uekawa.

They are placed under the GPL (see the header of each file for
details).

These files are scripts to help pbuilder run with the linux device mapper.

I hope the files are reasonably well commented. If not please ask me.

The order of things is roughly as follows.

1. Create/assign two block devices for build work. The BASEDEV device
   should have enough space to hold the basic debian buildd root
   (an unpacked base.tgz from pbuilder). The COWDEV device should have
   enough space to actually perform the build.

   WARNING: All data on these two devices will be wiped out
   in the process of using lvmbuilder. You have been warned.

1a.You could use a script like "sample_device_creator" to create
   two block devices. This creates "loop"back block devices out
   of files.

   WARNING: This is a sample script which I no longer use.
   Instead I have two real block devices reserved for build work.

2. You should edit your ~/.pbuilderrc and add two lines
	BASEDEV=<fullpath of base block device>
	COWDEV=<fullpath of cow block device>
   you can also give these on the command line with
	--basedev <fullpath of base block device>
   and
	--cowdev <fullpath of cow block device>

3. Edit the lvmbuilder script to give the location of the lib
   subdirectory.

4. After this you can use lvmbuilder in place of pbuilder for
   the "create", "update", "build", "login" and "execute" operations.
   A number of command line options of pbuilder do not make
   sense in the lvm context --- these should generate error
   messages. See the file STRATEGY for details.


Hope this helps!
