I have installed MySQL on my Arch Linux server. I moved the data directory to a place under /home, where my RAID volume is mounted. I noticed that mysqld will not start in this configuration by default since the systemd unit contains the setting
I want to override just this setting. I don't want to re-specify the
ExecStart or similar commands, in case they change when the package is upgraded.
I tried making a simple file at
mysqld.service and added only these lines:
This doesn't work as it looks like the service in /etc replaces, not overrides, the system service.
Is there a way to override settings in systemd unit files this way without directly modifying the files in /usr/lib/systemd/system? (which is what I have done for now as a temporary fix, although that will end up reverted if the package is updated)
