Bash has documentation. If implementation does not match documentation you can file a bug as much as you can against a POSIX-compliant shell. With bash being much more active project than most POSIX-compliant shells the bug is even much more likely to get resolved. And unlike POSIX-compliant shells bash has BASH_VERSION which tells you *exactly* what you are getting in case you need to support multiple versions that behave differently.
And if you're in need of writing shell scripts that are specific to bash versions, you're free to require /bin/bash as interpreter.
It is not always clear how to do that. I thought there is a way to switch rpm spec scriptlets to different shell but did not find how to do that for %build.Again, if you find yourself in need to write bash version specific %build scripts, write them in a real language - or at least put them in an extra script.
Anyway, if we provide alternatives for /bin/sh you can assume any shell
Yeah, that's right. *If* - *if* a shell in openSUSE wants to provide /bin/sh, it needs to eat all our rpm snippets that survived checkbashisms. Just because bash provides it, doesn't mean there are alternatives worth fighting over theoretic problems. And %build sections should potentially even be executed by /bin/bash --posix right away. But again, if your %build section is bash version specific, it's a lost case IMO. Greetings, Stephan -- A good name lost is seldom regained.
