Bug#1007263: Document upgrading dash will change the /bin/sh no matter what
Package: dash Version: 0.5.12-9 Followup-For: Bug #1007263 X-Debbugs-Cc: r...@debian.org This topic came up in Policy bug #1074014. It sounds like there is a plan to document the transition in the release notes, but, going forward, the mechanism to change the shell underlying /bin/sh sounds like it changed as part of the current work and users should now do a local diversion of /bin/sh and create a new symlink. I think it would be a good idea to add user-facing documentation explaining how to do that, and I wasn't able to find any in dash (or bash, which is the most likely but not the only target shell). It probably should be in more than just NEWS.Debian, as well, since this will continue to be something some users need to do going forward, such as to handle local #!/bin/sh scripts that have bashisms. Maybe the README.Debian file of this package would be an appropriate place? -- System Information: Debian Release: trixie/sid APT prefers unstable APT policy: (990, 'unstable'), (500, 'unstable-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 6.10.3-amd64 (SMP w/12 CPU threads; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages dash depends on: ii debianutils 5.20 ii libc62.39-6 dash recommends no packages. dash suggests no packages. -- debconf information: * dash/sh: true
