Use s2 at your peril!
slice 2 is the whole disk, you risk wiping your operating system.
All you have to do is use a slice that is not a swapfs slice, e.g. /var/tmp or make a directory /export/home/dump.

systemd.slice
SYSTEMD.SLICE(5) systemd.slice SYSTEMD.SLICE(5)
NAME
systemd.slice - Slice unit configuration
SYNOPSIS
slice.slice
DESCRIPTION
A unit configuration file whose name ends in ".slice" encodes information about a slice which is a concept for hierarchially managing
resources of a group of processes. This management is performed by creating a node in the Linux Control Group (cgroup) tree. Units that
manage processes (primarilly scope and service units) may be assigned to a specific slice. For each slice, certain resource limits may the
be set that apply to all processes of all units contained in that slice. Slices are organized hierarchially in a tree. The name of the
slice encodes the location in the tree. The name consists of a dash-separated series of names, which describes the path to the slice from
the root slice. The root slice is named, -.slice. Example: foo-bar.slice is a slice that is located within foo.slice, which in turn is
located in the root slice -.slice.
By default, service and scope units are placed in system.slice, virtual machines and containers registered with systemd-machined(1) are
found in machine.slice, and user sessions handled by systemd-logind(1) in user.slice. See systemd.special(5) for more information.
See systemd.unit(5) for the common options of all unit configuration files. The common configuration items are configured in the generic
[Unit] and [Install] sections. The slice specific configuration options are configured in the [Slice] section. Currently, only generic
resource control settings as described in systemd.resource-control(7) are allowed.
Unless DefaultDependencies=false is used, slice units will implicitly have dependencies of type Conflicts= and Before= on shutdown.target.
These ensure that slice units are removed prior to system shutdown. Only slice units involved with early boot or late system shutdown
should disable this option.
