If they are, then they are all broken. Try installing ash and linking it as /bin/sh
instead of bash. Then, try and reboot. Good luck, you will have to reboot again with
init=/bin/bash and relink bash as /bin/sh!
IMHO, the scripts should either be fixed to work with any standard sh, or have their
hashbang changed from #!/bin/sh to #!/bin/bash

IMHO, use bash-isms, as long as the script calls bash, and not sh.
