When the zfs-snapshot-bootfs service attempts to create a snapshot that already exists, the exit status of the command is non-zero and the service reports failed to the systemd service manager. This is a common occurrence if bootfs.snapshot is left set on the kernel command line and it should not be considered a failure. This service was originally set to ignore this error by prefixing the command with - on the ExecStart line, but the leading - appears to have been dropped in #13359.
