Subject: [PATCH 3/3] Make systemd-tmpfiles create MYSQL_DATADIR
|
|
|
|
This is a no-op if the directory exists, but makes sure it is created by
|
|
systemd-tmpfiles with proper permissions otherwise.
|
|
|
|
This solves packaging issues when the user MYSQLD_USER is created by
|
|
systemd-sysusers and uid is not known in advance.
|
|
|
|
Also this now sets the No_COW attribute.
