Package: debspawn Version: 0.6.0-1.1 Severity: normal Hi,
invoking debspawn build unstable foo.dsc runs the build after the /nonexistent directory has been created. I was able to pin that down to the call to execute_sdnspawn. It might well be possible that this is a bug in systemd-nspawn or systemd-run, but probably someone with more intimate knowledge of systemd-nspawn (you, the maintainer *grins*) has an easier job to debug this further. The builder user is created with /nonexistent as the home directory, and somewhere between the call to dsrun build-prepare and dsrun build-run one of the calls to systemd-nspawn -u builder creates the home directory of the user. This is bad because this disables the security effect of having an account's home directory point to a nonexistent directory, and also because adduser's autopkgtests fail in such an environment since adduser's autopkgtests test whether the special-case of /nonexistent (which adduser takes care to never create) is handled correctly. I have changed the call to adduser in dsrun and the setting of os.environ['HOME'] to /home/builder and was able to successfully run adduser's autopkgtest after doing a build --interactive. To make the changes effective, re-creation of the container is necessary (the account is only created once during container creation). It would be nice if the underlying bug in systemd could be fixed, declaring /nonexisting an exception, never creating it, or at least if the builder account in debspawn could be created with a different home directory to mitigate the painful results of systemd creating the directory.
