If you're at Lucid or Maverick, you can also create the rootfs img by
running the attached rootstock script.
Please install all rootstock dependencies by installing the official version
provided by the distro:
sudo apt-get install rootstock
Using the attached script:
sudo bash ./rootstock --fqdn beagleboard --login ubuntu --password temppwd
--imagesize 512M --seed ubuntu-minimal --dist lucid --serial ttyS2 --components
"main universe multiverse"
You'll get the rootfs img and the command that rootstock would call, that gives
the seg fault, e.g:
qemu-system-arm -M versatilepb -cpu cortex-a8 -kernel
/tmp/tmp.OxxUOBq4B0/qemu-vmlinuz -no-reboot -nographic -pidfile
/tmp/tmp.OxxUOBq4B0/qemu.pid -drive
file=/tmp/tmp.OxxUOBq4B0/qemu-armel-201007122016.img,aio=native,cache=none -m
256 -append 'console=ttyAMA0,115200n8 root=/dev/sda rw mem=256M
devtmpfs.mount=0 init=/bin/installer quiet'

Bug description:
Binary package hint: qemu-kvm
As I'm now implementing the support for creating a rootstock rootfs without
requiring root, I need to run the deboostrap' second stage inside a VM, to
correctly install the packages into the rootfs.
qemu-system-arm fails right after debootstrap finish the second stage, giving a
segmentation fault.
Command:
qemu-system-arm -M versatilepb -cpu cortex-a8 -kernel vmlinuz -no-reboot
-nographic -drive file=qemu-armel-201007122016.img,aio=native,cache=none -m 256
-append 'console=ttyAMA0,115200n8 root=/dev/sda rw mem=256M devtmpfs.mount=0
init=/bin/installer'
