What makes you say it's broken and needs fixing?

SlackBuild scripts have #!/bin/sh at the top, yes. But they only have
to work on Slackware. And, /bin/sh on Slackware *has to be* a symlink
to /bin/bash. If you don't believe me, try changing it to ash, ksh,
or zsh, then rebooting the box.

Personally I'd prefer if SlackBuild scripts started with #!/bin/bash,
but when I used to submit them that way, the admins would change it
back to #!/bin/sh. So I quit worrying about it, and the world didn't

Now, if the use of bashisms actually caused real problems (build
failures), that would be worth looking into. But changing a bunch of
scripts just to comply with what amounts to OCD... IMO not worth even
thinking about.

I'm just one opinionated guy though. What does the rest of the list
