Description=dlog logging service
Requires=local-fs.target
After=systemd-tmpfiles-setup.service local-fs.target
Before=basic.target
DefaultDependencies=no

# Note:
# Requires=/After= are added dynamically via dlog-unit-generator (see systemd.generator(7)) if logger
# devices are available.  This is required as dlog_logger has to have devices available and with proper
# permissions being set before it starts (as we run as 'log' user).

[Service]
Type=notify
#
# Setting TZ prevents logger from repeatedly statting /etc/localtime
# each time it wanted a timestamp, increasing performance (glibc feature).
# However, there is a tradeoff as it also sets the timezone in stone.
#
# We accept the tradeoff as without caching dlog_logger will be A LOT
# slower (eg. 30-60% slower). If you dare to touch setting below, be
# prepared to show vallgrind callgrind and perf data showing the
# performance penalty.
Environment=TZ=:/etc/localtime
