# Determine whether the volume is already a shared mount, so that the
# make-shared command below only runs (and only reports `changed`) when it
# actually needs to. We read /proc/self/mountinfo (always present on Linux)
# and look for the ` shared:` optional tag on the volume's mount point line.
# grep exits non-zero on no-match or any error, so the make-shared command is
# skipped only when shared propagation is positively confirmed; every other
# case falls through to running it (which is idempotent).
