this should be saved in the bug log.
cheers!

Practically speaking, I think bash is going to have to remain essential. There are innumerable scripts, package build rules, maintainer scripts, and other things in Debian referencing /bin/bash without declaring a dependency, particularly since that was one of the common solutions to bashisms in scripts when we did the cleanup to be able to support dash as /bin/sh. I don't think there's much to be gained by going through all of those and requiring them to declare a dependency, particularly given how much third-party Linux stuff also assumes that /bin/bash is always available. So, I think this reduces to whether or not dash needs to remain essential. I personally think that our default /bin/sh shell should be essential, and the reasons why we switched to dash for that still apply, so I'm comfortable keeping it essential. The problem with instead making "sh" essential is that we'd have to be very careful about what was allowed to Provide sh. Other people have discovered, for example, that zsh as /bin/sh has interesting and surprising issues that can break software that otherwise works with more common /bin/sh shells. If someone sets up their /bin/sh symlink manually to point to some other shell, more power to them, but allowing those shells to Provide sh the way that various awk implementations Provide awk promises somewhat more interoperability and testing than I think we can promise. -- Russ Allbery (r...@debian.org) <http://www.eyrie.org/~eagle/> -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
