Add SYSTEMD_READWRITEPATH-variable to mariadb{@,}.service.in to make sure that
if one is not building RPM or DEB packages then make sure there is ReadWritePaths
directive is defined in systemd service file.
This ensures that tar-ball installation has permissions to write database default
installation path (default: /usr/local/mysql/data) even if it's located
under /usr. Writing to that location is prevented by 'ProtectSystem=full'
systemd directive by default.
Prefixing the path with "-" in systemd causes there to not be an error if the
path doesn't exist. This may occur if the user has configured a datadir
elsewhere.

# It's not recommended to modify this file in-place, because it will be
|
|
# overwritten during package upgrades. If you want to customize, the
|
|
# best way is to create a file "/etc/systemd/system/mariadb.service",
|
|
# containing
|
|
# .include /usr/lib/systemd/system/mariadb.service
|
|
# ...make your changes here...
|
|
# or create a file "/etc/systemd/system/mariadb.service.d/foo.conf",
|
|
# which doesn't need to include ".include" call and which will be parsed
|
|
# after the file mariadb.service itself is parsed.
