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.
These are scripts to help pbuilder run with the device mapper or LVM.
(You do need "dmsetup" to be installed on your system.)
I hope the files are reasonably well commented. If not please ask me.
The rough order of things is as follows.
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.
2. You should edit your ~/.pbuilderrc and add two lines
BASEDEV=<fullpath of base device>
COWDEV=<fullpath of cow device>
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. 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!
