On one hand it's supposed to open a new session and change a number of execution context parameters (`<code>uid</code>`, `<code>gid</code>`, `<code>env</code>`, ...), and on the other it's supposed to inherit a lot concepts from the originating session (`<code>tty</code>`, `<code>cgroup</code>`, `<code>audit</code>`, ...). Since this is so weakly defined it's a really weird mix&amp;match of old and new paramters.</blockquote> +<p>Pretty clear, it ask for root or specified user password, launches a shell. If <code>-</code>, <code>-l</code>, <code>--login</code> is put it starts a new environement before starting the shell.</p> +<blockquote>To keep this somewhat managable we decided to only switch the absolute minimum over, and that excludes `XDG_RUNTIME_DIR`, specifically because `XDG_RUNTIME_DIR` is actually bound to the `session/audit` runtime and those we do not transition. Instead we simply unset it.</blockquote> +<p>Ah, of course desktop crap in the userland… And crappy explanation, maybe you should patent and copyreich that in case. ᕕ(ᐛ)ᕗ</p> +<blockquote><pre><code>$ cat /etc/os-release +NAME=Fedora VERSION="24 (Workstation Edition)" +ID=fedora +VERSION_ID=24 +PRETTY_NAME="Fedora 24 (Workstation Edition)" +ANSI_COLOR="0;34" +CPE_NAME="cpe:/o:fedoraproject:fedora:24" +HOME_URL="https://fedoraproject.org/" +BUG_REPORT_URL="https://bugzilla.redhat.com/" +REDHAT_BUGZILLA_PRODUCT="Fedora" +REDHAT_BUGZILLA_PRODUCT_VERSION=Rawhide +REDHAT_SUPPORT_PRODUCT="Fedora" +REDHAT_SUPPORT_PRODUCT_VERSION=Rawhide +PRIVACY_POLICY_URL=https://fedoraproject.org/wiki/Legal:PrivacyPolicy +VARIANT="Workstation Edition" +VARIANT_ID=workstation + +$systemctl --version +systemd 225 ++PAM +AUDIT +SELINUX +IMA -APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ -LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD +IDN</pre></code></blockquote> +<p>Okay here’s the same shit from a non voided system.
