1. Make logs available to journalctl (systemd's logging system) by not
specifying -daemonwait, which rightfully has its own set of stdout
and stderr descriptors (a user invoking with -daemonwait on the
command line should not see any logs). It makes more sense not to
daemonize in the systemd context anyway.
2. Make systemd aware of when bitcoind is started and in steady state by
specifying -startupnotify='systemd-notify --ready' and Type=notify.
NotifyAccess=all is necessary so that the spawned thread for
startupnotify is allowed to inform systemd of bitcoind's readiness.
Note that NotifyAccess=exec won't work because it only allows
sd_notify readiness signalling from Exec*= declarations in the
.service file.
3. Also make systemd aware of when bitcoind is stopping by specifying
-shutdownnotify='systemd-notify --stopping'
Note that we currently don't allow multiple *notify commands, but users
can override it in systemd via:
# systemctl edit bitcoind
By specifying something like:
[Service]
ExecStart=/usr/bin/bitcoind -pid=/run/bitcoind/bitcoind.pid \
-conf=/etc/bitcoin/bitcoin.conf \
-datadir=/var/lib/bitcoind \
-startupnotify='systemd-notify --ready; mystartupcommandhere' \
-shutdownnotify='systemd-notify --stopping; myshutdowncommandhere'
