# Initial script which is run inside of all qemu images. The first argument to
# this script (as arranged by the qemu image itself) is the path to where the
# libc crate is mounted.
#
# For qemu images we currently need to install Rust manually as this wasn't done
# by the initial run-travis.sh script
#
# FIXME: feels like run-travis.sh should be responsible for downloading the
#        compiler.
