I dug up some very old correspondence I had with Jude regarding why he
uses dash
I said
"however I dont have dash on my system so I
had to symlink it to bash to make vdev run
vdevd/helpers/LINUX/*.sh files"
Here is what he said then 2015-05-22 06:25
"That should be temporary. I'm currently going through the scripts to
make sure they work with Devuan's system shell (dash). When I create
the "-release" branch, I will switch back to #!/bin/sh."
