-The files in this directory (except pbuilderrc) were written by
-(C) 2006 Kapil Hari Paranjape <kapil@imsc.res.in>.
-They are placed in the public domain. You can do with them exactly as you wish.
+The files under this directory were written by Kapil Hari Paranjape
+<kapil@imsc.res.in> and are based on pbuilder by Junichi Uekawa.
-These are scripts to help pbuilder run with the device mapper or LVM.
-(You do need "dmsetup" to be installed on your system.)
+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 rough order of things is as follows.
+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.
-1. Use a script like "sample_device_creator" to create two block
-devices. The BASE device should have enough space to hold the basic
-buildd environment (an unpacked base.tgz from pbuilder). The COW
-device should have enough space to perform the build.
+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 device>
- COWDEV=<fullpath of cow device>
+ 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.
-3. Use a script like "sample_setup_base" to setup the BASE device.
-Essentially this ensures that BASE device has a working (ext2) file
-system which has the entire chroot (e.g. just unpack base.tgz to this
-device). In addition, the BASE device *must* be "e2fsck -f"'ed in
-order that the resize works in the next step. Optionally you can set
-the BASE device to be a read-only device after this step.
+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.
-4. Now you can run "lvmbuilder <dsc_filename>" to build your package.
- (a) It ought to be faster than unpacking base.tgz
- (b) It will make no changes to the BASE device.
Hope this helps!

+1. We require that the user has defined (either
+ in the environment or in one of the pbuilderrc
+ files), two devices:
+ BASEDEV
+ This is the device where the persistent
+ ext2 filesystem containing the basic build
+ file system lies (what is usually kept
+ in base.tgz). This file system should be
+ e2fsck -f clean. create/update/clean go here.
+ COWDEV
+ This is the device to which the writes
+ will actually go during the build/login/execute.
+
+2. For create/update/clean, we just mount BASEDEV in the appropriate
+ place and run pbuilder create/update/clean --no-tgz. We run an
+ e2fsck -f at the end.
+
+3. For all other operations:
+ a. we create a new device TOTALDEV consisting of BASEDEV
+ extended by zeroes by the size of COWDEV.
+ d. we create a snapshot version WORKDEV of TOTALDEV with
+ the writes going to COWDEV.
+ e. we resize2fs the filesystem WORKDEV. This
+ step could be *slow*.
+ f. we mount WORKDEV in the appropriate place and run
+ pbuilder with the appropriate command.
+ g. on exit or error we must unmount WORKDEV and
+ remove WORKDEV and TOTALDEV.
