Type=simple
# systemd expands %h (home) at parse time; env-var expansion in
# the ExecStart binary position is NOT supported. Retarget via
# `systemctl --user edit clawstor-fuse.service` if the install
# path differs.
#
# Pre-6d we ran ExecStartPre=mkdir + ExecStartPre=fusermount3-u-z
# to guard against stale mounts. On some Ubuntu builds (observed
# on morpheus 2026-07-14) that combination made systemd refuse
# the subsequent FUSE mount with EPERM even though a manual
# invocation of the same binary succeeded. The minimal form here
# — plain ExecStart, ExecStop = unmount — is what actually works
# reliably across the fleet. Create the mount point manually
# (mkdir -p ~/clawstor-mount) once before enabling this unit.
