Daniel, thank you kindly for your patience. It is much appreciated.
Here is a smaller set of patches today, drawn from your feedback.
git://github.com/utlemming/lb.git
0001-Adding-Ubuntu-Cloud-Images-package-lists.patch:
- Adds Ubuntu Cloud images packages list
0002-Adding-check-for-valid-mtab-during-chrooted-binary-r.patch:
- Installs and reverts /etc/mtab if missing
0003-Adding-foreign-bootstrap-via-qemu-for-cross-arch-bui.patch
- Adds LB_BOOTSTRAP_QEMU_*
The use-case for the foreign bootstrap via qemu is to build ARMEL images
on non-ARM hardware. While it is not exactly the fastest thing in the
world, it allows for some flexibility (i.e. not having to procure
separate hardware for separate builds). My use case is building ARMEL
images on a x86_64 cloud instance. In the last email you mentioned
trying it out. Should you feel so inclined, here is an example (albeit
useless) lb_config command.
Tested using lb_config commands of:
lb_config --package-lists ubuntu-cloud --mode ubuntu --initramfs none
--initsystem none --bootloader none -d oneiric -b rootfs
--build-with-chroot true --chroot-filesystem ext3 -a armel
--bootstrap-qemu-arch armel --bootstrap-qemu-static /usr/bin/qemu-arm-static
Thanks,
Ben
