Also, a row of bug reports have been created for adduser in result of the discussion that was initiated on debian-devel earlier this year. And there are real people, such as Matt, working on them, so adduser is going to get better. There is also a wishlist bug against policy clarifying account management in maintainer scripts. The bug reports also give a pretty good overview about what adduser will do, so interested package maintainers are invited to sift through them and maybe adapt their maintainer scripts. In addition, as one of the adduser maintainers, I am open to questions and suggestions. Greetings Marc -- - Marc Haber | "I don't trust Computers.

Yup, see also https://lintian.debian.org/tags/maintainer-script-lacks-home-in-adduser In https://wiki.debian.org/AccountHandlingInMaintainerScripts there are some ideas; I believe there is not yet final consensus in Debian on how to deal with adduser in maintainer scripts... Anyway HTH, Bye, Joost

adduser claims existing diretory in postinst when running piuparts for shiny-server
Hi, the Debian Science team has packaged node-shiny-server[1]. It creates a system user in its postinst script. I've added some debug output to this script[2] since I wanted to debug a piuparts issue which you can see here in salsa CI[3]. This log shows two ways to verify that the home directory of the user does not exist, but adduser fails with Stopped: Couldn't create home directory `/home/shiny': File exists. anyway. Any idea what's going on here and how to fix this? Kind regards Andreas.
