Seems to me that this is caused by the #!/bin/bash line in https://github.com/bonfire-networks/ember/blob/a4556d5a366c7f3621f5187e1c3f14d16ff9aadc/install.sh#L1 - it will not work on the systems where bash is installed somewhere else.

Any special requirements for install.sh? I think it would be easy to rewrite it in plain Bourne shell...

rough plain sh version of ember install.sh, no need for functions.sh
