# Trigger rmtfs.service when the qcom_rmtfs_mem device node appears.
#
# /dev/qcom_rmtfs_mem* is created by the rmtfs-mem kernel module when the
# modem shared-memory region is probed.  The exact boot time at which this
# happens depends on whether the module is built-in or loaded as a module and
# on the systemd target ordering, so a static ConditionPathExists check in the
# service unit is not sufficient – the service must be (re-)triggered by udev
# whenever the device shows up.
