Bashisms are very common in Netkit scripts

[sv75]

All netkit scripts are '/bin/sh', still they have a lot of bashisms (use 'checkbashisms' to know how much exactly).

I believe it is better to just replace '#!/bin/sh' with '#!/bin/bash' in all netkit scripts, The another way is to remove all bashisms one by one.

In Ubuntu and Debian '/bin/sh' does not point to '/bin/bash' by default, btw.
