Package: dbconfig-common Version: 1.8.52 Severity: wishlist Dear Maintainer,
If connection to the database server fails on postinst of a dbconfig-common package, it currently just prints an error. It would be great if dbconfig-common could write out a SQL file with all the commands it wanted to execute (including CREATE DATABASE / CREATE USER) to a well-defined location so that the administrator may easily rerun this once the database server is available again. The error message shown should contain the path of the file and the command the administrator should execute once the server is up. Two use cases (as per our discussion at DebConf): - remote servers may be down during the installation of a dbconfig-common utilizing package - but the administrator might want to use dbconfig-common here to simplify the setup - and having to just run a simple command they can copy/paste from the error message once the server is up again would be simpler than manually configuring the package - provisioning of VMs/Containers: in some setups, containers/VMs can be provisioned automatically (via script) by debootstrap'ing into a chroot, then dropping a /usr/sbin/policy-rc.d there to disable service starts and then installing all packages. For the vast majority of packages this works, but obviously the database server won't be running in this case, so dbconfig-common won't work there. If dbconfig-common were to just put SQL files for all applications that use the database to some well-defined location, one could add support to the provisioning script to manually run them at a later point - so that installing everything there would still work automatically. It would be great if dbconfig-common could support that. If you have further questions, feel free to contact me.
