No /var/lib/dpkg/info/dash.preinst in Buster In < it's required to run the following command in chroot environment: /var/lib/dpkg/info/dash.preinst install This command runs in Stretch, however there is no `/var/lib/dpkg/info/dash.preinst` file found in Buster. What might be the equivalent command to complete the installation in Buster? # Reproduction git clone cd multistrap-example ./build.sh buster

`dash.preinst` was removed a year ago, because it was no longer necessary — its purpose was to ensure that `/bin/sh`’s ownership could switch between `bash` and `dash`, but `bash` stopped shipping `/bin/sh`.

The equivalent command is nothing, you don’t need to run the `preinst` any more.
