Provide static-sh alias name and ship busybox-static by default
Binary package hint: busybox
for the boot recovery spec  we want to add a static shell for disaster recovery. If
e.g. libc is broken a stock ubuntu system can currently not be booted. I would like
to add busybox-static to the default install  and make it provide a "/bin/static-sh"
that can then be used to boot with "init=/
Please let me know what you think and if static-sh is good or too generic as a name.
