NOTE: When using the systemd .service file, the creation of the aforementioned
|

directories and the setting of their permissions is automatically handled by
|

systemd. Directories are given a permission of 710, giving the bitcoin group
|
||||
access to files under it _if_ the files themselves give permission to the
|
||||
bitcoin group to do so (e.g. when `-sysperms` is specified). This does not allow
|
||||
for the listing of files under the directory.

NOTE: It is not currently possible to override `datadir` in
|
||||
`/etc/bitcoin/bitcoin.conf` with the current systemd, OpenRC, and Upstart init
|
||||
files out-of-the-box. This is because the command line options specified in the
|
||||
init files take precedence over the configurations in
|
||||
`/etc/bitcoin/bitcoin.conf`. However, some init systems have their own
|
||||
configuration mechanisms that would allow for overriding the command line

options specified in the init files (e.g. setting `BITCOIND_DATADIR` for
|
||||
OpenRC).

systemd init file
|
||||
=========
|
||||
|
||||
The systemd init file (`contrib/init/bitcoind.service`) has been changed to use
|
||||
`/var/lib/bitcoind` as the data directory instead of `~bitcoin/.bitcoin`. This
|
||||
change makes Bitcoin Core more consistent with other services, and makes the
|
||||
systemd init config more consistent with existing Upstart and OpenRC configs.
|
||||
|
||||
The configuration, PID, and data directories are now completely managed by
|
||||
systemd, which will take care of their creation, permissions, etc. See
|
||||
[`systemd.exec (5)`](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#RuntimeDirectory=)
|
||||
for more details.
|
||||
|
||||
When using the provided init files under `contrib/init`, overriding the
|
||||
`datadir` option in `/etc/bitcoin/bitcoin.conf` will have no effect. This is
|
||||
because the command line arguments specified in the init files take precedence
|
||||
over the options specified in `/etc/bitcoin/bitcoin.conf`.
