Fix fake sudo to preserve argument quoting

The fake sudo script used $@ without quotes, which broke commands like: sudo sh -c “dd bs=64K …” The -c argument lost its quoted string, causing dd to silently do nothing and exit 0.

Use exec “$@” to properly preserve argument quoting and propagate the exit code.

This project contains scripts and configs to create a small bootable Linux image, primarily for the purposes of testing Manila.

It uses buildroot to do nearly all of the hard work.

The built Linux image is optimized for size, and targets the i386 platform under QEMU.

The following extra features are enabled:

SSH server
NFSv3/4 server
NFSv3/4 client
Samba4 Server
CIFS client

== Dependencies needed ==

On Ubuntu:

To build

sudo apt-get -y install curl unzip bc python quilt parted qemu-utils
build-essential gcc-multilib

For test/dev

sudo apt-get -y install bison flex texinfo gettext ncurses-dev sshpass
qt-sdk qemu-kvm genisoimage

On Fedora:

To build

sudo dnf -y install curl unzip bc python quilt parted qemu-img gcc-c++
make glibc-devel.i686

For test/dev

sudo dnf -y install bison flex texinfo gettext ncurses-devel sshpass
qt-devel qemu-kvm genisoimage

== Building the images ==

To build both images run:

./run-buildroot.sh

== Cleaning up ==

To nuke everything and start over:

rm -rf buildroot output* overlay* sudo rm *.qcow2
