processes running during a soft-reboot operation requires disconnecting the service comprehensively from
the rest of the OS, i.e. minimizing IPC and reducing sharing of resources with the rest of the OS. A
possible mechanism to achieve this is the concept of <ulink
- url="https://systemd.io/PORTABLE_SERVICES">Portable Services</ulink>, but make sure no resource from
- the host's root filesystem is pinned via <varname>BindPaths=</varname> or similar unit settings,
- otherwise the old root filesystem will be kept in memory as long as the unit is running.</para>
