sh-utils depends on bash for the nohup command, which runs just fine
with /sib/sh with the following change to the last line in the script
(copied from debian's nohup, which uses /bin/sh):

-exec -- "$@"
+exec "$@"

I would imagine most other bash dependencies are just like this;  bash
run as /bin/sh still allows bash syntax, and many Linux /bin/sh scripts
are really bash-specific.  It's easier to simply change the bang path
to /bin/bash and add a dependency than it is to fix the script.
