[Touch-packages] [Bug 1915936] Re: systemd-coredump user is create by something other than its derived systemd packages
Home Directory¶ The home directory for a new system user. If omitted, defaults to the root directory. Only applies to lines of type u and should otherwise be left unset (or "-"). It is recommended to omit this, unless software strictly requires a home directory to be set. systemd-sysusers only sets the home directory record in the user database. To actually create the directory, consider adding a corresponding tmpfiles.d(5) fragment. ** Tags added: seg sts -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1915936 Title: systemd-coredump user is create by something other than its derived systemd packages Status in systemd package in Ubuntu: New Bug description: systemd-coredump binary package is instructed as follows: #debian/systemd-coredump.postinst: adduser --quiet --system --group --no-create-home --home /run/systemd \ --gecos "systemd Core Dumper" systemd-coredump But one doesn't need this package to be installed to have the systemd- coredump user created.
