It works for me in latest main:

# systemctl cat test at .service
# /etc/systemd/system/test at .service
[Service]
RootImage=/usr/share/minimal_0.raw
ExecStart=sleep infinity

[Unit]
SurviveFinalKillSignal=yes
IgnoreOnIsolate=yes
DefaultDependencies=no

# systemctl cat system-test.slice
# /etc/systemd/system/system-test.slice.d/foo.conf
[Unit]
SurviveFinalKillSignal=yes
IgnoreOnIsolate=yes
DefaultDependencies=no

With these, test at foo survives a soft-reboot. I guess this should be
documented in the manpage, I'll take care of it.
