`bitcoind` can take a long time to flush its db cache to disk upon
shutdown. Most init files send a `SIGKILL` after a timeout of 1 minute,
causing unclean shutdowns and triggering a long "Rolling forward" at the
next startup. Increasing this timeout to 10 minutes should reduce how
often this occurs, especially during IBD.
fixup! Set ProtectHome in systemd service file
Tell systemd to create, set, and ensure the right mode for the PID,
configuration, and data directories.
Only the exec bit is set for groups for the aforementioned directories.
This is the least privilege perm that allows for the
reading/writing/execing of files under the directory _if_ the files
themselves give permission to its group to do so (e.g. when -sysperms is
specified). Note that this does not allow for the listing of files under
the directory.

OpenRC changed their program binary names in 2014 (3 years ago), and using the old names has loud warnings now

16be7dd Improve bitcoind systemd service file (Florian Schmaus)
Pull request description:
Add comment how further options can be added or existing ones
modified. Use /run/${RuntimeDirectory} for PID file.
Remove TimeoutStopSec, TimeoutStartSec, StartLimitInterval,
StartLimitBurst directives as those should be set indivdually.
Remove Group to user the bitcoin user's default group.
Changed Restart from 'always' to 'on-failure' (can also be overwritten
individually).

This allows users to specify, e.g. raise, the default timeout of 60
seconds. Some bitcoind instances, especially long running ones on slow
hardware, require a higher timeout for a clean shut down.
Also add a comment to bitcoind.openrc's 'retry=', since it is not
obvious from the variable name what it does.
